Hastings fennel

2012-07-17 11.38.07

Coming out of Hastings station car park today I caught sight of a fine stand of fennel (Foeniculum vulgare) and stopped to take a snap out of the car window.

The flowers are very attractive to a wide range of insects (grow them with one of the taller varieties of mint in a herb garden and you will have a wonderful insect party on sunny days when both are in flower).

The leaves and seeds can, of course, be used in a wide range of recipes and herbal teas.

Fennel is not a native British plant but hails from the Mediterranean.  However, it has been happily established here probably since Roman times.

I have read that it inhibits the growth of other plants, but there is clearly a large number of perfectly healthy plants growing next to it here, so I take it that it does not normally, if ever, have this quality.

It seems a fitting sort of plant to have seen on the day the Olympic torch arrives in Hastings.  A stately species originating from the Mediterranean and mixing well with other plants.  It even seems to be approaching the fence as a kind of high jump.  Apropos of the Olympics, our eight year old granddaughter on being told that the Olympic flame was transported by coach from place to place, was concerned that the vehicle might go on fire.  A blazing bus would certainly be a newsworthy story.

Hedge woundwort

Standing idly in the garden in a rare sunny moment, I noticed a bank of flowering hedge woundwort (Stachys sylvatica) was attracting many hive and bumble bees to its flowers.

20120705 Stachys sylvatica SV

The plant is common and widespread in our area and elsewhere in Britain and has a solid reputation as a bee plant.

It also has, or had, medicinal virtues.  Nicholas Culpeper, the renowned 17th C herbalist wrote that this plant "stamped with vinegar and applied in manner of a pultis, taketh away wens and hard swellings, and inflammation of the kernels under the eares and jawes."

Thomas Green (1832) in The Universal Herbal says "Toads are thought to be fond of living under its shade" which, coupled with its attraction to bees and its curative properties, gives me a good excuse not to cut the plant down.  Even more so as the Ecological Flora of the British Isles lists 56 insect species associated with the plant, including 5 that are monophagous as well as (snap) 56 fungi, mostly rusts, moulds and the like.

If my arithmetic is right that is 112 species but this does not include visitors to the flowers.  In contrast, Anne Pratt in her book Wild Flowers (1860) writes "no animal is known to eat it, save the snail" but I take it that (apart from molluscs) she was referring to mammals.

Return to Shirley Moor

Back on the Moor again today,  Bit warmer, but still not exactly 'flaming June'.

I ventured a little further down the footpath leading due east from just beyond New Bridge, past marsh mallow and waving false oat grass along the dyke side.

At the end (TQ9450132026) I found a plant of swinecress, Coronopus squamatus, growing in the corner of the field and looking like a vegetable starfish.  It is a species I have come across from time to time before, but never growing quite so flat as this.

20120614 Coronopus squamatus 2

A little further on was a rickety bridge and the path continued up the hill through a wheat field towards Appledore.  I think anyone would have been reminded of the lines from Rudyard Kipling's poem Puck's Song.

See you the dimpled track that runs
All hollow through the wheat?
O that was where they hauled the guns
That smote King Philip's fleet!

Though I hope no one had been hauling guns up the hill with the intention of smiting anyone here.

20120614 Wheat footpath, Shirley Moor

To the south another series of ditches snaked away towards the rising ground picked out the lacy white flowers of hemlock water-dropwort, Oenanthe crocata.

20120614 Oenanthe crocata, Shirley Moor

The plant is poisonous in all its parts.  Indeed, the 18th century botanical illustrator Georg Dionysius Ehret, claimed that he was nearly overcome by its fumes when he was drawing the plant in a poorly ventilated studio.  I hope the combine harvester doesn't gather it along with the wheat.

Urban grasslands

Perceptive readers will note that this post was written out of sequence. Several sections in the overall colloquy have been compiled before this one. This because I only today finished checking on the names of some of the plants I found, but more of that later.

This is about a very short walk taken from the upper car park at the Tesco superstore in Church Wood Drive to Ingleside, a road lying some 80 metres to the west beyond the houses and the woods.

‘Ingleside’ is a curious name that has been much used in Britain and America for hotels, rest homes and street and road names rather than full-blown settlements, though there is a village in Illinois called ‘Ingleside’ and also a suburb of Sydney in Australia. The word mainly seems to be a Scots term for a fireside, rather like ‘inglenook’ and ‘ingle’ is said to derive from Scottish Gaelic aingeal meaning in one of its senses fire, light or sunshine.

Although the word was often used in the past in various contexts, it was brought into greater prominence by children’s author Lucy Maud Montgomery who wrote Anne of Green Gables. Two of her later books were Rilla of Ingleside (1921) and Anne of Ingleside (1939). Ingleside was the name of the house in these novels which were set in North America and, for those familiar with the books, the word is full of the kind of romantic associations that might help to promote a new housing estate. Chapter 2 of Rilla opens:

Outside, the Ingleside lawn was full of golden pools of sunshine and plots of alluring shadows. Rilla Blythe was swinging in the hammock under the big Scotch pine, Gertrude Oliver sat at its roots beside her, and Walter was stretched at full length on the grass, lost in a romance of chivalry wherein old heroes and beauties of dead and gone centuries lived vividly again for him.

In Anne of Ingleside Montgomery wrote:

I love the name Ingleside. It's such a nice, homey name. That's what Gilbert said. We had quite a time deciding on a name. We tried out several but they didn't seem to belong.  But when we thought of Ingleside we knew it was the right one.

It is always possible, of course, that a road name refers to a person rather than a place. Ingleside does not, however, appear to be in use as a personal name in the United Kingdom though a book by E. V. Lucas called Mr Ingleside and set in England was published in 1910. Indeed, it may have been this that consciously or subconsciously inspired Lucy Maud Montgomery to use the house name in her novels. There may also, of course, have been a house in the vicinity of Tesco called ‘Ingleside’ and it further strikes me that ‘Dingleside’, ‘dingle’ meaning a small wooded valley, might have been a more appropriate name.

Having written all that I discovered that a small estate west of Tesco and accessed from Ingleside is called ‘Inglewood Gardens’ making ‘Ingleside’ a reasonable choice for the name of nearby main road. However, since the main road was there before the housing estate, it would seem that the gardens was named as an allusion to the main road, leaving us exactly as we were before. Interestingly, to me at any rate, ‘Inglewood’ as in Inglewood Forest, Cumbria, means ‘wood of the Angles (or English)’ and therefore is of a completely different linguistic origin than ‘Ingleside’.

Taxonomic considerations not quite aside, Ingleside runs through the ancient Church Wood and it is ironic that one of the roads carved out of this precious and irreplaceable habitat is called Cubitt Way, presumably as an acknowledgement of the role the housing company Cubitt & West had in the development of this estate.

My walk took me along a twitten between the back gardens of Coneyburrow and Inglewood Gardens and a short stretch of woodland before reaching the road. Despite some accumulation of rubbish, the woodland still maintained some of its earlier character with celandines, anemones, yellow archangel, wood spurge and other plants characteristic of ancient woodland under a canopy of hornbeam and ash.

On the way back to the car park, my eye was caught by a triangle of grass on the south eastern corner of the Coneyburrow Gardens estate. The quite closely mown and rather sparse sward had a remarkable variety of plant species: annual meadow-grass, bird’s-foot trefoil, buck's-horn plantain, cat's-ear, changing forget-me-not, common fleabane, common mouse-ear, common ragwort, common stork's-bill, creeping buttercup, curled dock, cut-leaved crane's-bill, daisy, dandelion, field madder, gold-of-pleasure, groundsel, hairy bitter-cress, lesser stitchwort, lesser trefoil, meadow buttercup, narrow-leaved vetch, red clover, ribwort plantain, sorrel, sweet vernal-grass, wall barley, wall speedwell, white clover, wood dock and many which I am sure I will have missed.

20120522 Sward near Tesco

One of the more interesting species is wild madder, Sherardia arvensis. Despite scouring my books and the Internet I can find nothing medicinal about it and concur with F. E. Hulme in his Familiar Wild Flowers (1906) who wrote “It is indeed a curious fact that this Sherardia is one of the very few plants that the mediaeval herbalists and simple-mongers seem to have found no healing virtue in.” (I like the idea of being a ‘simple-monger’) . However, it seems rather unlikely that it would have been given the name of ‘madder’ if it had not had some connection with dyeing and in a Manual of Weeds by Ada E. Georgia (1914) the author writes “The fleshy roots, though much inferior to the true Madder, are sometimes used for the production of a red dye.”
IMG_0144

Other areas of sward in the vicinity were much less diverse and I am sure the soil for this triangle must have been imported from a not too far distant chalky location near the sea. From the car park there were two ways up to it, one a flight of steps, the other a long path with a hairpin bend to make access possible by wheel chair. Near the bend someone had earlier spilt a tin of sweet corn on the asphalt, decorating the path with what looked like a rash of septic pustules, or maybe a scatter of gigantic pollen grains.

Coda

On 9 June I walked round Inglewood Gardens, a strangely small and isolated modern estate. It was very quiet, I saw only one human being in the middle of a Saturday afternoon and there were few sounds of traffic or people.

Much of the estate was embellished by areas of lightly mown grass and many of these were quite similar to the species rich triangle just to the north. Ecologically interesting, but out of place in an area that used to be ancient woodland. Indeed a remnant of this woodland can be seen in the background of this picture of Inglewood Gardens below.

A little snipefly

This morning I found a little snipefly, Chrysopilus asiliformis, in our garden.  A very colourful insect which seems not uncommon in Sussex.

20120607 Chrysopilus asiliformis SV

Stubbs & Drake in British Soldierflies and their allies (2001) say "Adults may be seen sitting on leaves", certainly the case with this one as it spent some time on a leaf of one of my houseleeks.

Its life history is still, I believe, unknown, but other members of the family are largely carnivorous and occur in decaying wood and soil.

Shirley Moor, Kent.

Today I explored Shirley Moor via Moor Lane (OS grid ref: TQ9382432035). A thin post-heatwave mist dulled the early summer air on either side of the scything tarmac fringed with cow parsley, buttercups and the rising wands of false oat-grass. There were little clumps of trees dotted about: oak with an understorey of blackthorn, ivy and sallow, sheltering a myriad of noisy birds undeterred from their spring business by the coolness of the day.

20120530 Shirley Moor (9)

At one point the ground rose as the lane ascended the small hill on which Glover Farm and Shirley Farm are situated. Once this was probably an island in the marshy water world of the Moor, like Red Hill and Chapel Bank to the south. A red-legged partridge ran across the road and, from a gateway, I could see over the green barley to the rolling fleeces, darker green, of the distant Heron Woods. It was so still there was no shaking of the barley by the wind.

Yellow remnants of oil-seed rape blossomed round the edges of fields. An old blue pickup vehicle full of men appeared and bumped slowly away down an unmade, arrow-straight farm road. After it had gone I moved on to New Bridge that carries Moor Lane across the Cradlebridge Sewer (the small streams that meander across the flat lands around Romney Marsh and the lower parts of the Wealden river systems are widely named ‘sewers’ though they are no more polluted than any other English river. The word is ultimately descended, via Norman French from Vulgar Latin exaquāria meaning simply a drain for carrying water off).

20120530 Shirley Moor New Bridge (20)

The views from this spot could hardly have been more variable. To the north the lane ran straight as an arrow towards my newly discovered ‘island’. Southward a curving screen of tall white willow above a band of lacy cow parsley followed the line of the lane which was of two-tone grey asphalt, darker in the centre where wheels did not run, verged by bright green grass – a five-banded landscape.

20120530 Shirley Moor New Bridge (19)

To the west were bare, flat fields ultimately broken by a line of dead and dying trees bordering a distant dyke.

20120530 Shirley Moor New Bridge (17)

To the east, in total contrast, was a magical composition of England in early summer. A swan, a haughty swan, rested on its reflection in the black and silver water of the Cradlebridge Sewer, just in front of a thick pollarded willow and between banks whitened by billowing stands of hemlock water-dropwort with, at one place, a cluster of the flowers of yellow flag caught in the sallow and reed. The only sound was from the small birds in the bushes and the endless lark song embroidering the upper air; the only smell that of fading, falling hawthorn blossom, the small petals turning from white to pink when their work was done.

20120530 Shirley Moor Cradlebridge Sewer (15a)

I found a feather here, of a partridge I think, beautifully and strikingly patterned with at least six shades of brown, the darkest making tiger stripes along the central rachis. I wished I had had a Tyrolean hat to put it in.

Somewhere towards the Isle of Oxney a cuckoo called.

The bird on the wall

I was in Waterworks Road, Hastings and I noticed this mural phenomenon.

20120522 Cymbalaria & graffiti Hastings (44)

The plant is a rather fine example of ivy-leaved toadflax (Cymbalaria muralis) but I thought the splash of white paint was also very striking, looking rather like the head of a slavering wolf.

It was only after I got home that I noticed the black bird in the position of the wolf's eye.  Quite plainly this has been drawn here as it is not the same colour as the bricks (you can also see the 'wolf's head' on Google's Street View and the bird is not there).

I suspect it has something to do with the Hastings & Bexhill Wood Recycling Project which has a workshop a few yards up the road where they make, among other things, nest boxes and wooden seagulls.  Or maybe it is a Banksy miniature: he has, after all, worked in the Hastings area.

A circumnavigation

There is something grand and philosophical about a circumnavigation. It suggests that, via a certain trajectory to a farthest point, a wanderer can return through different ways to a place that is by definition where she started from.

There are heroic orbits around the earth, the solar system, the British Isles and modest ones around the park or the boot fair or, though not usually classified as species of circumnavigation, a passage through a selected tangle of streets on a local perambulation. I once took a circuitous route along lanes encompassing numerous Gloucestershire farms in the Forest of Dean by walking from Coleford through Millend and Clearwell and Newland and Lower Cross back to Coleford.

The conquest of a supermarket car park may be classified as a collection of one of the rarer taxa in the circumnavigation genus since, perhaps, it is not perceived as terribly interesting. Nevertheless it was my project for the day and one that could make a modest but valuable contribution to psychogeography. And one never knows what any circumambulation might reveal.

Today my field of study was Morrison’s car park adjacent to Queens Road in Hastings. I set off from the main entrance heading north and immediately my eye was caught by a baby’s dummy in colourless plastic lying on the ground. It evoked an image of an obstreperous infant propelling the article over the side of the pram like a trainee hammer thrower.

Around the corner I could see the embankment where the trains ran, their engines sending an echoing Whee–e-e in crescendo or decrescendo as they left or approached the station. Underneath the trains a red banner on the wall proclaimed “We buy direct from 5,000 British livestock farmers.” Takes a lot of farms to feed Hastings.

Semi-mature trees were growing from gravelly, brick-edged rectangles of the car park leafing in reddish or green ochre while in the corners of this area there were dense billows of clipped, evergreen laurustinus with some groundsel and annual meadow grass flowering hopefully underneath. On the other side of the main entrance road was an ancient, low sandstone wall adjacent to a small lawn with a whitebeam tree. The wall must be a survivor from a time when this area was completely different. Part of a house perhaps along the Old Roar stream now safely culverted below the modern town. Elder was growing by the wall and on the opposite side of the lawn questing trails of goosegrass pushed through dense cotoneaster bushes.

There was a large buddleia by the recycling point: huge metal boxes for glass, shoes, plastic bottles, newspapers, electrical items. Behind a curious, almost secret, concrete path led in a curve to a closed brown door. There was ivy on the ground, under the bushes, climbing the walls. The plant evidently likes it here and tries to escape the ivy police who are forever pulling it down.

In the north east corner by Queens Road a lonely birch spreads its elegant figure above a chewed up mat of shredded bark and wood, perhaps the start of a shrubbery reconstruction. There was more cotoneaster by the parking bays: undulating cushions of dark green foliage spattered with pinkish white flowers aiming to greet a spring that hadn’t really arrived.

At the garage the ground changed. Red brick paviors for the pedestrian areas, brown with white speckles in the area intended for refuelling cars. By the entry sign to this refuelling area a large gorse bush was in flower. Difficult to believe this was planted, especially as it seemed to be a one off, so it must have found its way in as a seed on a car or a bird and now tries to hide among the alien ornamentals. On the south garage corner a hybrid whitebeam, a few shoots of travellers joy and two herring gulls with a wary look that said “is he a threat or a food provider.” Beyond this were extensive low-growing beds of grey-leaved brachyglottis shrubs extending like urban chaparral through a gap between buildings to Brook Street and the Prince Albert pub, though one would have had to walk round through the car park pedestrian entrance to reach either of these two places.

By the far wall Prunus laurocerasus ‘Otto Luyken’ was already in flower below a brick wall and a fine complex of moss-covered roofs sloping at different angles. Above these windblown muddled clouds in infinite shades of grey sweeping eastwards. May is the season of white petals: their falling can be mistaken for snow when the weather is cold.

Squirrel in the houseleeks

It has been cold so far this May, but yesterday the sun shone for a while and the grey squirrel that skitters round our garden took a sunbathing nap on a wooden shelf where I keep some of my houseleeks.  I see squirrels every day, but this is the first time I have seen one basking.

20120514 sleeping squirrel

The Sempervivums behind are, from right to left, Black Mountain, Green Ice, Blood Tip and S. atlanticum.  The plant in the pot at the rear is a Deptford pink, Dianthus armeria, put on the shelf to stop the rabbits eating it.

Hastings steps

Hastings in East Sussex UK has many flights of steps ascending the various hills around the town.

Noonan’s Steps climbs like a waterless cascade up the flank of the West Hill.

20120508 Noonan's Steps Hastings (2)

The walls and crevices support many different plants, wet and shiny after the overnight rain. There are ivy-leaved toadflax and trailing bellflower; elder and sycamore bushes; shepherd's purse, goosegrass and clumps of moss casually thrown off neighbouring roofs by insect hunting birds.  The photo below is of some alexanders, Smyrnium olusatrum, hanging over a wall:

20120508 Alexanders Noonan's Steps (5)

At one spot there was a battered typewriter lying in a doorway next to an empty can of Red Bull. Maybe an aspiring writer had thrown it and the empty can from an upper window in frustration when the muse would not visit. Whatever the case, no novels, or poems, or letters were going to emerge from its keys again. It seemed strange though that it had survived for so long in this computer age.

20120508 Old typewriter Noonan's Steps (4)

For typewriter aficionados it is a Commodore, probably made in Canada.  Taxonomy has got me!

I walked back down Gas Works Steps and up Stonefield Road. 

20120508 Gas Works Steps hastings (9)

Here, as in lots of other place, were some good examples of a sprawling  Cerastium.  It is, I think, sea mouse-ear, C. diffusum but I will have to do a bit more work on that as it a difficult genus.

20120508 Cerastium Hastings (10)

I also found a spray of oak-leaved honeysuckle, I think just a juvenile form of our ordinary wild honeysuckle, Lonicera periclymenum.

By the Tesco superstore, Hollington, Hastings.

On the eastern side of Tescos superstore there is an asphalt path running uphill over mown grass to the streets and houses on the Tilekiln estate. To the west is ancient woodland, a northern extension of Church Wood still with yellow archangel peeping under the chestnut post and rail fence and with plenty of bluebells beneath the leafing hornbeams and other trees.

On the other side of the path it is mostly mown grass up to the fence round the Tesco buildings, but in the middle of this is a deep gully that was once the bed of a stream running into the lower part of Church Wood but now culverted for much of its length (Grid Ref. TQ7861311733). It is rather encouragingly full of a very varied scrub and I imagine the species count would be high if an extended ecological survey were undertaken.

20120505 (19)

There were fresh green brambles, white ball-bearing buds of hawthorn, oak and ash entwined with honeysuckle and flowering sedge while, in the distance, a woodpigeon was cooing persistently.

On the edge of the gully I found a fine plant of spotted medick (Medicago arabica) with tiny, yellow flowers.  I is native in southern Britain that is said to be expanding its range for reasons that are not entirely clear. It seems to be widespread in Sussex.

20120505 (20) 

In several other places were plants of ribwort plantain (Plantago lanceolata) with their rough, pod-like flower heads already developed (see behind the medick above). I saw some being used in a masterchef salad on television the other day and the authors of the Walk around Britain website say “The fresh seeds of both species make a very good protein nibble, tasting rather like mushrooms.” I tried a flower head. It didn’t taste bad, but had a rough, chaff-like quality making it difficult to swallow.

Two teenage girls and a boy were wandering about clearly trying to think of something to do. They chattered loudly and talked a bit about me, a stranger, but were good humoured and cheerful when I made some irrelevant reply. They made no further remarks after they had seen me eating ribwort plantain flowers – I can’t think why.

St George's mushrooms

Driving round our lane I noticed a couple of flashes of white in the grass verge and, upon investigation, discovered they were St George's mushrooms, Calocybe gambosa.

20120505 (13)

Interesting to see toadstools among anemone and wild strawberry leaves.

This is an edible species that regularly appears along these lane verges and named after St George because it is a spring fruiting fungus that often appears around St George's day, 23 April.

I have eaten them in the past and they are quite popular in many parts of mainland Europe, but I don't really care for them.  Maybe I'll see what flies I can breed out and whether they differ from those that burrow about in our autumn fungi.

Beware Ceanothuses crossing!

This photo of a lonely flowering Ceanothus bush escaping from Tescos in St. Leonard's-on-Sea came out of my camera today.

20120505 (18a)

Ceanothus is a North American plant belonging to the family Rhamnaceae.  The buckthorns, the only foodplants of our British brimstone butterfly larvae, also belong to this plant family.  The adult butterflies are known to visit Ceanothus flowers in this country and I wonder if anyone has looked for caterpillars on this plant, or tried to feed them on the leaves.

Rats!

I was asked recently by a friend if there was anything he could do about the rats that had turned up on the ground under his bird table.

20120217 Rat 6

Cats, terriers, traps, guns, poison, ultrasonic devices- there a plenty of options, most of them with drawbacks. And, of course, he could stop feeding the birds.

The rodents there are brown rats (Rattus norvegicus) which, despite the specific name, did not reach Britain from Norway. They arrived here and elsewhere in Europe, from their native home in the Far East, probably in the early 18th century and have spread to most of the world apart from the Arctic and Antarctic and a few islands.

In Britain some reckon there are 81 million of them, more than the human population and many, of course, live in urban areas. They have a bad reputation because they steal our food (as well as that of the birds), forage in smelly places and can transmit various diseases, especially when they live in sewers. They do, however, have a plus side. Some people think the decline of bubonic plague was due to the arrival of brown rats since, like us, they can apparently catch plague but not transmit it. Transmission was normally accomplished by fleas on the black rat and other rodents and the displacement of the black rat (Rattus rattus) by the brown rat has been equated with a decline in the plague (aka black death).

Rats have also contributed much to medicine through their role as laboratory animals and in many countries they are popular pets.

The disgust felt for these animals by many people seems to be a culturally derived habit and not one like a fear of things that can be genuinely harmful like venomous snakes. Their name has also been used as a widespread insult -"You dirty rat" etc. Maybe they are too much like us. Many people do have a sort of general fear of wild animals, even mice and spiders, but the rat is in a class of its own.

Robert Browning in the Pied Piper of Hamelin didn't do much for their image:

They fought the dogs and killed the cats,
And bit the babies in the cradles,
And ate the cheeses out of the vats,
And licked the soup from the cooks' own ladles,
Split open the kegs of salted sprats,
Made nests inside men's Sunday hats

But the puppet Roland Rat, created by David Claridge, has had a spectacular career as a TV character since the 1980s and his markedly ratty personality and home in a ratcave under Kings Cross station seems to make him more rather than less popular. It is us that are peculiar creatures rather than rats. Still, we both go in for bruxing (the sound made by grinding one's teeth), a new addition to my vocabulary.

Winter sunset

For 12 days the night time temperature has fallen below freezing with over a week of unbroken snow cover. In the garden on several days it has reached -6 degrees C, and once -8, unusually cold for our area. It was snowing again this morning, but a thaw is forecast so hopefully it will feel a little warmer next week.

Yesterday evening the temperature fell very rapidly as the sun went down. There was an Irish tradition of a small ‘western room’ in the house where mementoes of members of the family that had passed on were kept so that one was reminded of them as one faced the setting sun, the direction the dead followed on their journey to the Otherworld.

The coldness and stillness of the subzero winter world echoed this mood as I watched the sun set over the churchyard across the valley from our garden. However, the dark 'sunspot' of a rook's nest silhouetted against our life giving star reminded me that spring is not far away.

Galls in the grass

Strolling yesterday on the fringes of St. Leonard's-on-Sea I noticed some of the fading grasses dangling through a wire mesh fence were swollen and distorted at the tips where the flowering spike might have been.

20111218 Tetramesa hyalipennis 007

Further investigation showed that the grass was common couch grass (Elytrigia repens) and that the galls were caused by the small Eurytomid wasp Tetramesa hyalipennis.  The books and papers on galls indicate that this is a widespread and common species but there are no records on the Sussex Biodiversity Record Centre database and the National Biodiversity Network has records only from Merseyside and Northern Scotland.  It has also been recorded from Cornwall and I am sure it has simply been overlooked elsewhere.

Now is the time to get out and see if you can find any.

I have brought those in the picture home to see what hatches out.  It will not necessarily be T. hyalipennis as various parasites and squatters have been recorded from these galls and the child or children of the original gall causer may have been consumed in its prime.

Moth from alder buckthorn

A few weeks ago I found some leaves spun together on the alder buckthorn (Frangula alnus) in our garden and managed to raise the moth from the caterpillar it contained.

I had hope it might be an alder buckthorn specialist, but it turned out to be the common light brown apple moth (Epiphyas postvittana). 20110820 SV Epiphyas postvittana

It is an introduced species from Australia that was first found in the UK in Cornwall in the 1930s Apparently the larvae will eat almost anything, though they are an apple orchard pest in their home country.  There they also feed on a wide range of native species as well as introduced fruit trees.

I wonder if this might be the first record of the moth using alder buckthorn.

Wool-carder bee

A welcome resident in our garden is the wool-carder bee (Anthidium manicatum).  There is a male that defends a territory around some of my houseleek (Sempervivum) collection.  Both males and females seem particularly fond of the flowers and there is a nest in the corner of one of the pots.

20110731 South View Sempervivum 018 The picture above is of a male sitting on a plastic watering can.  Quite often he will take to the wing, fly round the area and hover in front of the houseleek flowers, occasionally settling on them.

The male is, unusually for insects, larger and more aggressive than the female depicted below.

20110731 South View Sempervivum 012

The name 'wool-carder-bee' derives from the fact that the female strips hair from wooly plants, rolls them into a ball and flies off with this tucked between her chin and her forelegs.  She uses this wool to line her nest hole and then constructs cells which she fills with a mixture of pollen and honey for her brood.

Gilbert White of Selborne wrote about this species in his journals: "There is a sort of wild bee frequenting the garden-campion for the sake of its tomentum, which probably it turns to some purpose in the business of nidification.  It is very pleasant to see with what address it strips off the pubes, running from the top to the bottom of the branch, & shaving it bare with all the dexterity of a hoop-shaver."

I imagine the 'garden-campion' was the  rose campion (Lychnis coronaria).  Hoop-shaving was the woodland craft of cutting hoops (for binding barrels and so on) from hazel poles.

White oak midget

A week ago I found a mine in the folded edge of an oak leaf on a tree growing near the end of Billingham Lane, Udimore (first field trip of the new Udimore Wildlife Society).

20110723 Phyllonorycter mine & pupal skin 020

I identified it tentatively as being caused by the white oak midget moth (Phyllonorycter harrisella) and kept it in a box to see if anything emerged.  I was rewarded today by this tiny but beautiful insect hardly bigger than a grass seed.  Its pupal case can be seen in the top photo.

20110723 Phyllonorycter 018

Like many insects, the eye spots at the end of the wings create a false head which is more likely to be attacked by a predator allowing the moth to escape relatively unharmed.  The wing stripes also seem to make it point in the wrong direction.

Leaf miners like this usually appear only in very small numbers on their host plants, an I wonder why this should be when there is so much food available.  The infamous horse-chestnut leaf miner (Cameraria ohridella) which is a species of about the same size and in the same family - Gracillariidae - was first recorded in Britain in 2002 having spread rapidly from the Balkans.  Although it was described as a new species only in 1986, specimens in herbarium collections of horse-chestnut date back to 1879 but it was well-behaved until very recently.  Cameraria now seems unstoppable and every single leaf on every horse-chestnut is often infected with several mines.  Why do our long-standing native species like the white oak midget show such commendable restraint?  Is it due to parasites, predators or pathogens that Cameraria does not yet have?  Some believe it is and that the current massive infestations of horse-chestnut will decline as the years go by.

Of course, the relative scarcity of the white oak midget with, say, only a few mines per oak tree may be an advantage inasmuch as it makes it quite difficult for predators and parasites to find it and hardly worth the energy-wasting search for such a small morsel.  That makes me wonder about the dynamics and practicality of remaining at a low-level without being wiped out altogether.

Beetle bug (Issus coleoptratus)

I have again been running one of my log pile traps at the  end of the garden.  There was quite a good haul of invertebrates today and I took a photo of this little beetle bug sitting on top of the pile.

This species is common everywhere and often found on ivy.  I always see it around rotten logs and am still trying to work out what it eats.

Woodpecker & tortoiseshell

We see all sorts of things in the garden from our sitting room window: rabbits, foxes, weasels, badgers and all manner of birds and insects.

Today we were given two special treats.  First a green woodpecker spent some time on our small lawn, pecking with evident relish at something in the grass.

20110527 Green woodpecker 004

It was not possible to see what the bird found so tasty, but there were some light showers overnight, and this may have brought a few insects to the surface in these drought-stricken days.

The other treat was a small tortoiseshell butterfly (Aglais urticae) enjoying the nectar in a large flowered clematis.

20110527 A urticae on clematis 014

Such highly engineered blossoms don not, generally, seem to be much visited by insects, but the butterfly returned repeatedly and, as far as I could see, visited no other flowers.

The small tortoiseshell has suffered a massive decline in recent years and it is thought this is due to a parasitic tachinid fly called Sturmia bella, first recorded in  Britain in the late 1990s.  However, the butterfly seems to be making a comeback and several were seen in this area last year after a period of total absence.  I wonder how it has managed to outwit the parasite, if that is what was causing the problem.  perhaps like the holly blue and its parasitic wasp, the large number of caterpillars affected means that eventually the parasite almost runs out of hosts and becomes scarce, only to return in force as the abundance of the butterfly increases.

Blue tits away

The blue tits in the nest box just outside our bedroom window are now fully fledged.  One of the young ones poked his head through the hole to explore the possibilities of the outside world.

Bluetits Sempervivum 001

He seemed to like the look of what he saw, pulled his wings out and flew off into the bushes by the hedge.  No practice, no licence, just instinct.

Edward T. Connold - an appreciation

clip_image002

Recently, while compiling some notes on the mites of Sussex, I was made aware of the detailed observations made by Edward Connold on the gall mites of the area around Hastings where he lived in the late 19th and early 20th centuries. Many of these still stand as the only recorded observation of a particular species in Sussex, though most are probably widely distributed. Connold seemed an interesting man, so I thought I would find a little more out about him.

Edward Thomas Connold was born in Castle Street, Hastings in June 1862 and died in St Leonards-on-Sea in January 1910 aged 47. Although he moved about to various schools and in various jobs as a child and a young man, he returned permanently to St. Leonards in 1885. His son, Edward Thomas Connold, was a professional photographer who did much work in Sussex.

Connold, an amateur (he earned his living as a grocer), had a very wide interest in natural history as is borne out by his various observations in The Hastings and East Sussex Naturalist. He was especially interested in shells, wasps, caterpillars, wildflowers and marine life but his major contribution nationally and internationally was in the study of plant galls and Margaret Redfern in her New Naturalist book Plant Galls (2011) suggest he was the discoverer of galls on the roots of plants.

Detailed notes on the galls Connold found are published in his books British Vegetable Galls (1901), British Oak Galls (1908) and Plant Galls of Great Britain (1909). He also made a valuable contribution to the study of marine life by editing his friend Philip Rufford’s book Notes of British Hydroid Zoophytes (1902). (Hydroid Zoophytes are now included in the phylum Bryozoa, or moss animals. They are small, mainly marine animals often similar to corals with creatures like small sea anemones inside a colonial, skeletal covering of their own construction. Many colonies look more like plants than animals. Rufford and Connold often obtained their specimens of these and other marine life from the Hastings trawlers.)

In 1907 Connold also described and photographed the colony of ‘larger wintergreen’ (now round-leaved wintergreen) that then flourished “in the Hastings District” (Connold, 1908). This was presumably the plant from the Icklesham railway cutting (TQ856174) discovered by a Mrs. Wood in 1901. He was also one of several people who claimed that the smooth snake (Coronella austriaca) occurred in the Hastings area along with adders and grass snakes and something he referred to as the ‘small red viper’. Once formally named Vipera rubra, these are now known simply to be young adders that are often of a reddish colour (Beebee & Griffiths, 2000).

clip_image004

Something of Connold’s personality and character emerge from his book of essays Gleanings from the Fields of Nature which he describes thus:

The studies are from copious notes, mental and written, made during very many enjoyable rambles along the shore, and through woods and by-paths of rural districts around Hastings and St. Leonards-on-Sea; and from careful examination of the objects under the microscope.

He had a soft spot for spiders:

While it is admitted that spiders about the house are not welcome, and that they also suggest neglect, by spinning their snares in nooks and crannies, they often rid the occupants of the home of many troublesome flies.

But decidedly old-fashioned attitudes towards the digging up of primroses:

The primrose is a hardy plant, and will not suffer from being properly removed from its native haunt, and placed in a garden or rockery.

Connold, like the rest of us, made the occasional mistake (he described wild service leaves as guelder rose, for example) but he was a first class recorder who in his short life left us an important legacy on species in the Hastings area over 100 years ago. In one of his obituaries The Gardeners’ Chronicle said “his work on Vegetable Galls is a valuable contribution to the advancement of science.”

His writing was clear and usually to the point, though sometimes he would allow himself an engaging Edwardian conceit:

And perhaps some frisky little billow flings itself upon a large boulder nearby, and laughs with glee as it suddenly breaks into countless beads of spray, and showers them upon you like liquid pearls. (Connold, 1908b.)

An explosive plant

clip_image002

Alder buckthorn (Frangula alnus) is an unassuming shrub or small tree that is not uncommon in woods and on heaths in England and Wales. Its main claim to attention today is that it is one of the principle food plants of the brimstone butterfly (Gonepteryx rhamni) but it has had an important role in the past in the fortunes of this and other European countries through the use of its charcoal in the manufacture of gunpowder. Alder buckthorn charcoal ignites readily and burns evenly and slowly. As well as for cartridges, its steady-burning properties were exploited in manufacturing fuses for explosives (Mauskopf, 2006).

Alder buckthorn grows quite widely in my home area around the village of Sedlescombe in East Sussex, UK, mostly occurring in woodlands. I have come across a few plants, in Brede High Wood for example, that appear to have been coppiced, but I think coppice plantations of this small tree were not established locally in the past. However, as the following paragraphs will indicate, it seems highly likely that the wood was harvested as a valuable item of underwood for converting to gunpowder charcoal, either locally or further afield.

The value of alder buckthorn charcoal for gunpowder dates back many years and it has been described as being of “major military importance in the 15th to 19th centuries.” (Mobile Reference, 2010). In 1785 Major William Congreve (later Sir William) carried out tests on the charcoal from various woods and in 1791 listed alder buckthorn (as black dogwood), alder and white willow as the best types to be used in gunpowder production. Writing in 1831, Elizabeth Kent said that the charcoal made from the wood was “much prized by the manufacturers of gunpowder, who buy up all they can procure of it, and use it only for the very best gunpowder.”

Part of the reason why the economic role of alder buckthorn was obscured is that its vernacular names were confusing. John R. Jackson, curator of the museum at Kew, wrote in 1870 “In most books relating to economic botany, or to the application of woods,Cornus sanguinea, or dogwood, is referred to as yielding the best charcoal for gunpowder. Certain it is that the gunpowder makers all know the wood they use in such large quantities, by the name of dogwood, and it was generally believed that Cornus sanguinea was the plant which furnished them with their supplies.” At that period, samples of ‘dogwood’ used for gunpowder charcoal in many different places were sent to Kew and all turned out to be alder buckthorn. Jackson continued that this was proof that alder buckthorn “is the plant from whence the gunpowder-makers draw their supplies, and that Cornus sanguinea, or true dogwood, is never used, now, nor, indeed is there any proof that it ever has been, for the powder makers maintain that what they now call dogwood is the same wood which has always been used by them.”

This confusion of names has been compounded by the scientific name of alder buckthorn changing from Rhamnus frangula to Frangula alnus in the last century.

Alder buckthorn is uncommon in Scotland but, in about 1870, the Royal Botanic Gardens, Edinburgh was sent a sample of alder buckthorn (as dogwood) from the Roslin Gunpowder Mills of Hay, Merricks & Co. in Midlothian. It was “of English growth in the county of Sussex” where the price varied from £10 to £14 per ton, according to quality. The sticks, which were usually sent out in May or June, were peeled and packed into bundles of 100 (M’Nab, 1870).

The Merricks family, who established the Roslin Gunpowder Mill in about 1805, originated in East Sussex “near the gunpowder mill sites at Battle and Sedlescombe” though no evidence has been found that any of the Merricks worked at these mills (Crocker, 1996). However, it may be that they took a knowledge of alder buckthorn charcoal with them to Scotland plus a knowledge of how to procure it.

In her book about Sedlescombe, Beryl Lucy (1978) says “the charcoal for ordinary gunpowder was made from alder wood burnt in pits in the way that had been practised locally, in Petley Woods in particular, from time immemorial. For the finer or sporting powder, dogwood was used. Both of these woods are still very plentiful in our countryside. When the underwood in the district was being cut, the dogwood was carefully reserved, peeled and tied into bundles.”  Alder buckthorn is not uncommon today in the Petley Wood area of Sedlescombe, while true dogwood (Cornus sanguinea) does not occur naturally in this part of East Sussex.

Another important gunpowder mill was that of John Hall & Son at Faversham in Kent and they apparently worked in conjunction with Hay, Merricks and Co., of Roslin to produce the only explosives of the gunpowder type which successfully passed the Woolwich tests for the " Permitted List." (International Congress of Pure and Applied Chemistry, 1909).

Hall’s works at Faversham spread over six hundred acres planted with both alder and alder buckthorn “more especially of the former, for though the wood itself is not so valuable as the latter for the actual manufacture of powder, the tree is, owing to its larger size, more effectual in obstructing fragments of burning timber as well as diminishing the force of the shock in case of an explosion.” (Jackson, 1870).

As an illustration of the quality and importance of alder buckthorn charcoal, Mauskopf (2006) writes “Fine Grain powder was replaced by Enfield Rifle (E.R.) powder in 1859; the grain size of the new powder was increased from 16-36 mesh to 16-24 mesh. But the chief modification was the change of wood for the charcoal: ‘dogwood’ was substituted for alder or willow. In a footnote to this passage Mauskopf, referring to a Major Morgan of the Royal Artillery, writes “The substitute was, in fact, alder buckthorn (Rhamnus frangula), known in France as bourdaine, the traditional source of charcoal for French military powder. Since the comparative on gunpowder of the chemist J.-L. Proust, published early in the century, bourdaine was known to yield a strong powder.”

In the earlier part of the 19th century alder buckthorn was obtained chiefly from Suffolk, Norfolk, Essex and Kent (Jackson, 1870) “but after the introduction of the Enfield rifle into the military service of this country, the superior kinds of powder came much more into demand, and it was found difficult to obtain a sufficient quantity.” Because of this, supplies of the wood were imported from mainland Europe, particularly Holland, Germany and Belgium. The charcoal was prepared in enclosed iron cylinders (Saturday Magazine, 1886).

During World War I the difficulty of obtaining alder buckthorn charcoal from mainland Europe meant that supplies had to be sought within Britain. The War Office appealed for wood in Gardeners’ Chronicle in 1915 saying they “would be glad to know of any supplies of Rhamnus Frangula in this country. Estate owners who have plantations of Rhamnus and are willing to sell should communicate with the Secretary, War Office, Whitehall.” (Anon., 1915) This was followed in the same magazine a few months later by a longer article from E. M. Holmes, a pharmacist and botanist from Sevenoaks, Kent. He said, among other things (Holmes, 1915):

· The wood of this small tree is at present much wanted for the manufacture of fine gunpowder. Formerly it was imported from Germany, where apparently the tree was coppiced in order to get straight stems.

· Wood about one inch in diameter is required.

· Those who know where the tree grows in fair abundance should make known the fact.

· The wood is recognised by the manufacturer by having a reddish stain around the small pith which the wood of Cornus does not possess.

· The bark, when scratched with the finger nail or a knife blade, shows a crimson colour underneath. .

· In view of the present difficulty experience should teach the necessity of cultivating Rhamnus Frangula in woods in this country.

Charcoal from alder buckthorn remained important for munitions until the close of World War II. According to Meiggs (1949):

"The Home Timber Production Department undertook responsibility for the supply of alder buckthorn (Rhamnus frangula) needed for the manufacture of a highly specialised form of charcoal used in the making of certain types of explosive. Before the war supplies had come from France and Czechoslovakia, but in 1938 small scale orders had been placed with the Forestry Commission and had been met from the New Forest. .... It was ... plentiful enough in the New Forest for economic production and it was in the New Forest that the first war demands were met and the basis of the standard organisation laid.

The sticks were cut in 2½-foot lengths, bundled in the woods and brought to a picking up point from which they were transported to a central depot. The sticks had to be peeled, which could only be done easily while the sap was up in the spring. As the demand increased, however, production had to be maintained over the whole year; outside the natural peeling season, the sticks were first boiled in a copper for up to an hour to make peeling easier and then laid out for two or three days to dry, before being again bundled, weighed and despatched. The same organisation was repeated when new depots were opened and women made this small but important sphere their own. The operations at the depot were organised by a specially selected measurer and the peeling and other work of the depot was carried out entirely by women. Women also eventually became exclusively responsible for locating supplies in the woods and for supervising the cutting to ensure that the cutters made no mistakes in identifying the somewhat rare shrub.

The demand grew rapidly as the munition programme got into its stride. Only 50 tons had been ordered in 1939. The requirement for 1940 was 200 tons, increased in 1941 to 400 tons, and fresh areas had to be opened up. Wicken Fen was the first outside the New Forest to be exploited, and following a survey of East Anglia, operations were extended to the neighbouring counties. In 1941, since these two main sources were becoming exhausted, a complete survey was made of the country by the Cambridge School of Botany for the Biology War Committee. Much useful information was gathered in the course of this survey on the ecological habits of the plant and the areas of main concentration were tabulated. ....

With the extension of operations a new peeling depot was established in the north west, drawing supplies from the neighbouring Divisions, but by the middle of 1943 sufficient stocks had been built up to call a halt."

Despite the value and importance of its charcoal, alder buckthorn seldom seems to have been grown as a crop in Britain, most supplies being gathered from self-sown plants scattered through the underwood. Sir Joseph Hooker, director of Kew Gardens in the late 19th century, did recommend that it was grown on a coppice system and this seems to have happened in the Faversham area, but this was almost certainly the exception rather than the rule. In some places today the plant is particularly abundant, Broadwater Forest near Tunbridge Wells, for example. This area was much used by the military in the past and it may be that the tree was deliberately encouraged.

In addition to its importance for gunpowder charcoal, alder buckthorn had a role in medecine and in the production of the artist's pigment known as sap green. Kent (1831) wrote “The juice expressed from the berries being boiled down with some gum arabic and a little alum, and then poured into bladders to grow hard, is the colour called sap green.”

Alder buckthorn bark and berries have long been used as a powerful laxative. Though this largely seemed to have stopped during the 19thcentury as gentler aperients became available, the bark was used for its purgative properties during World War II. Meiggs (1949) wrote “The bark was dried on corrugated iron sheets over improvised burners and ultimately found its way into purgatives. This was no secret to the gypsies who for centuries have eaten the berries or chewed the bark of alder buckthorn in preference to the more expensive and synthetic purgatives provided by the chemist; the use of the bark for this purpose, however, only became a respectable war demand when other sources of supply were reduced.”

Lizards in the parlour

Quite unexpectedly, two full grown common lizards (Zootoca vivipara) have appeared just outside our French windows.

20110325 SV lizards Udimore map 013

We have all been watching them sunning themselves on the steps and disappearing into various cracks in the wall and behind the masonry.

They seem very tame and one of them ventured briefly over the door sill and into the sitting room.

I do wonder where they have come from.  The last lizard I saw in our garden was five or six years ago when one used to visit the Square Metre.  The new pair must have come some way to their new home and it is good to see them.  If male and female, let's hope them have a family.

Hazel catkin galls

Now, with the weather improving, is the time to walk out and look for galls on hazel buds and catkins.

In my garden and round about, practically every hazel bush has big bud galls made by the mite Phytoptus avellanae.

20110309 SV Phytoptus avellanae 1

A more detailed search quickly revealed some galled catkins.

20110309 Contarinia coryli on hazel 016

The unopened brown catkin on the right has been attacked by either the mite Phyllocoptes coryli or the Cecidomyid midge Contarinia coryli.  The only way one can tell which species is responsible is by picking them apart and looking for the mites, which are minute, or the small white grubs of the midge.  I quite quickly found midge larvae - little white maggots - but have not found any of the mites yet.  They are very small though and will need a microscope.

Galls like this (the only two found on hazel catkins in Britain) are probably common throughout Britain, but rarely recorded, so if you come across any, don't forget to send records in.

The nut bud moth (Epinotia tenerana) also lives, in its earlier instars, in hazel catkins before boring its way into hazel buds to complete its development.  It is also widespread in Britain, so that' another one to look out for.

England's forests for sale

The much broadcast government consultation on the proposed sale of large parts of the estate owned by the public via the Forestry Commission was launched today:

http://www.defra.gov.uk/corporate/consult/forests/index.htm

Apart from saying, in the style of Sellar & Yeatman "This is a bad thing" (which I believe profoundly that it is), I thought I might use this space to set out some considerations that I have not seen covered in the media, but are important.

This is just a start. I will update this entry as time goes by.

30 January 2010

There is a very well considered commentary on the proposed forest sell-off from the Chief Executive of the Sussex Wildlife Trust, Tony Whitbread, here: http://www.sussexwt.org.uk/blog/2011/01/forestry-commission-sell-off/

27 January 2010

Access. The Government says that access will be conserved. Does this mean that new owners will be under an obligation to maintain car parks and footpaths and, in particular, any open glades or heathy areas that are so important for biodiversity? Will rides have to be maintained at an appropriate width for optimum ecological benefit? Will there be 'close seasons' when shooting takes place, or the birds to be shot are breeding? Will 'access' mean the freedom to go anywhere in the wood or forest, or will it be confined to set paths and routes?

Identification. How will we know if a wood or forest has public access or not? Currently Forestry Commission Woods are clearly marked on the popular Ordnance Survey Explorer and Pathfinder maps. If these woods are sold and the Forestry Commission marking removed, how will people know which woods are accessible? Perhaps the Government could consider continuing to mark them on maps some how or other. "Former public wood sold to a private owner by the Coalition Government in 2011."

If all the Ordnance Survey and other Government maps have to be changed, I wonder if the cost has been taken into account.

Many Forestry Commission properties have a sign at the entrance(s) so that people know there is access. Will the new owners have to erect signs saying that the wood/forest is one of the free access ones?

Is there the quite interesting danger that, in the absence of any positive information, people will assume that most or all woods have access? If challenged when walking, could the appropriate response be "Oh, I thought this was one of the public woods you had bought from the Government."

Is this a good moment to press for the 'Right to Roam' to be extended to woods and forests?

Shooting. I mentioned shooting above and, unless shooting is absolutely forbidden in any sold off woods/forests, it seems likely to escalate. Apart from the dislike of this pursuit by so many who use the countryside, it is likely to represent both a danger and a reason to deny access to woods. Many who have been in France know the tyranny in the French countryside of 'La Chasse' and its powerful lobby.

There is also the question of noise. The countryside where I live has been relatively peaceful for the last several years, but this could change with the dismal sound of organised shot gun fire reverberating around during the shooting season. This unpleasant effect extends, of course, far beyond the woods and forests where it is taking place.

Management. There has been much talk of management. It may be possible for an experienced woodland/forest manager to be employed on the larger properties. Most of the smaller ones are too small to justify such an expense. Organisations like county wildlife trusts, the RSPB or the Woodland Trust have managers that cover a number, often a large number, of woodland properties spread over a wide area. The input of experienced people from the Forestry Commission who cover large areas will, presumably, no longer be available and the management of small woods will suffer as the new owners are unlikely to have the time or money to invest in the long learning curve and multiple skills needed to know how best to deal with a wood.

Countryside stewardship. If the scheme continues, many of the sold off woods could be eligible for Entry Level or Higher Level Stewardship. Among other things this means they will receive payment from the Government provided they stick to the agreed management plan. I wonder if the cost of this has been taken into account in considering the 'profit' from woodland/forest sales.

Deer control. In many places deer, and also wild boar, are increasing. Their control via fencing and culling are complicated operations requiring cooperation over large areas if they are to be effective. Many of the animals are using smaller woods and increasingly coming into gardens as different, and often only partially successful, strategies are used to control them. If they are not controlled (and some new woodland owners might not want to) some woods may, in the long run, turn into wood pasture and, ultimately overgrazed grassland with starving animals and not much else.

Robber flies and hogweed larvae

Today as I was watering my house leeks a kite-tailed robber fly (Machimus atricapillus) landed on our abandoned refrigerator (circa 1935) and enjoyed sucking the juices via the head of a hapless hoverfly it had just caught.

20100804 Wbx & South View 030

Not far away I found some caterpillars of the fuscous brindled flat-body moth, Depressaria pastinacella, a common species but one that normally remains closely concealed in a spun together head of hogweed.

The weasel's lunch

Today I decided to have my lunch looking out into the garden.  Suddenly a weasel emerged from the undergrowth only a couple of metres from me and crossed our small patio.  She held her head high as she was carrying a dead mouse, as cats carry a kitten,  in her mouth.

We do occasionally see weasels in the garden, going along the hedge bottom or elsewhere, but I have not noticed one for several years past and think, like many creatures, they must be getting rarer.

Maybe the mouse was her lunch, but as she was carrying it elsewhere, I like to hope she has a family somewhere in our garden.
