Attached is a photo of a fly taken on 10 June in Trench wood, Worcestershire on Bramble, which we have id'ed to Trixia conspersa. Is that likely to be right? Unfortunately there is no specimen.
It looks right, but it could be a number of other species - hard to tell from a single, very small picture. The date and location are OK for Trixa (incidentally not Trixia) conspersa, which is widely distributed and not uncommon.
I think the photo was a casualty of the recent maintenance work on this website, apologies for that. I have now re-linked it and it should be available at larger size.
