A Lauxaniid
Taken recently near my home in Wiltshire, I believe this to be the Lauxaniid Homoneura biumbrata. Am I wide of the mark?

Re: A Lauxaniid
On the basis of the wing markings and veins I think that it is Opomyza florum.

Re: A Lauxaniid
Thank you, Brian - I agree. The problem I've often found with acalypterate keys lies with the costal break. The break in this specimen is hardly to be distinguished from the slightest of costal narrowing - certainly not a distinct break. I dislike having to rely upon i/d features, like the existence and location of the break, which cause one to spend hours at the eyepiece.
