The latest of these from UTB-land was Pine Beauty, from Chiltern Open-air Museum (last week, with Dave Morris and Rob Payne):
Yesterday I spent an hour wandering around Stoke Common, near Fulmer, Bucks. Sweeping the Heath and Heather with a sweep-net, I collected lots of bits of plant debris, out of which crawled couple of Coleophora pyrrhulipennella:
A lot of these were found on the new Birch leaves:
I think they may be Coleophora serratella, but can't be sure. The dark shape of the caterpillar can be seen reaching into the leaf-mine. Whether the greenfly is a friend or not, I don't know. I was a bit surprised to come across an adult Cydia ulicetana - I didn't think they were out, yet. But this one was.There is plenty of Gorse, the larval foodplant, around.
