Trixia conspersa?

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.
