Hawthorn (Crataegus monogyna) in flower

The flowering of the may is, to some pagans, a signal that Beltane has arrived, that summer has started. I like this as starting summer at Midsummer on 21 June seems rather odd.

So I offer you the hawthorn flowers photographed on May Day, 1 May, in Brickwall Deer Park, East Sussex, England.

Tree mallow hopper, Eupteryx melissae

Another discovery from my epic field trip to the suburbs of Bexhill-on-Sea. In an abandoned garden I found many large plants of tree mallow, Lavatera arborea. Their leaves were an unusual whitish green (see top picture), undoubtedly the effect of locust-like numbers of the plant hopper Eupteryx melissae that flew from the mallows in clouds evey time one of the plants was shaken.

This hopper, which also feeds on labiates, has not often been recorded in Sussex and,though I have frequently come across tree mallow, I have not seen the insect before.

People sometimes ask how I identify some of these more obscure insects. In a case like this where the species is clearly associated with a plant whose name I know I usually go to the Ecological Flora of the British Isles.

Under tree mallow there are only two options among the insects that enjoy eating this plant and one of them is a leaf hopper (Cicadellidae) called Eupteryx melissae. There are some pictures of this on the Internet and I get confirming details from the Royal Entomological Society's Handbook on the Cicadellidae.

Red cage fungus, Clathrus ruber

Walking down to the village shop in Sedlescombe, East Sussex today I was surprised to see a perfect fruiting body of a red cage fungus, Clathrus ruber.

It was growing among grass at the base of a hedge by a well trodden path close to the main road and it is the first time I have ever seen one.

Roughly the size of a tennis ball, this strange vegetable is a type of stinkhorn and does have a very bad smell to attract the flies that spread the spores found in the gooey black slime inside the lattice. From a distance it did not look like a living thing at all but more of a convoluted and twisted piece of plastic the product, maybe, of a 5 November bonfire.

The red cage is another one of these 'Mediterranean' species that are extending their range supposedly due to the warming of the climate and has followed very much the same route as the ivy bee, Colletes hederae, appearing first in the Channel Islands then later along the south coast and the West Country. I have not yet found any previous Sussex records, but I am sure there are a few and would be interested to hear from anyone if they know of any.
