Today and tomorrow are scheduled for a national British event called the Garden BioBlitz organised by a mixture of volunteer wildlife experts and enthusiasts with help from all over the place. See:
I spent a few hours revisiting the wildlife in the top half of our garden (so as to keep all records within the TQ782188 grid square) and submitted almost 150 records, something that rather understates the biodiversity of our home plot.
I took various photographs on my rounds and I think this first one sums up how rich a garden can be.
Elsewhere I saw a red-headed cardinal beetle (the 'sun' is a buttercup), here just about to launch into flight.
Although the mushroom season seems far away, there is a fairy ring of St. George's mushrooms in a grassy place halfway down the garden. We ate some the other day in the Spanish/Basque dish revuelto de perretxikos (perretxikoa is Basque for 'mushroom' in case you did not know that dear reader).
