Stigmella myrtillella

Last year, Sam and Nick posted on the Gwent blog about finding this leafminer on Bilberry in VC35, and since then I've been keeping an eye out for it in Glamorgan. Chris Jones and I had a quick search at Seven Sisters on Friday and found two vacated mines.


This seems to be the first VC41 record, though it is doubtless under-recorded as it needs to be specifically looked for and this usually means a hands-and-knees search. The mines we found are probably first generation mines, so there should be a new crop of mines from the second generation over the next few weeks. These should be visible until the Bilberry leaves drop in October/November.
