Just don't know where to start here.
Thanks, Sarah

It's a Muscidae or, more likely, an Anthomyiidae.
That's where my expertise ends.

I think that trying to take several views (dorsal and lateral) may improve success for such difficult flies. I read that it's possible to recognize Muscidae/Anthomyiidae families (i) by veins A2 and A1+CuA2 in the dorsal view (A. - reach wing margins, at least as fold; M. - not ..., these veins are short) and by the presense of sub-apical cell (A. - absent, M. - present) and (ii) by comparison of calypters' sizes in the lateral view (M. - lower calypter is larger than upper one; A. - lower calypter may be less than upper one or absent). Am I right?
BTW, I didn't find images with general wing venation schemes (and comprehensive descriptions) in the internet... Where is sub-apical cell?
Sincerely, Dima

Dima, what is the source of your characters dealing with the subapical cells?

Paul, I've just compared families by the Delta-intkey program with the key which ink-file I found in the "Downloads" section. Other characters I found there, too. I've checked also some other (more simple) keys in the internet, but didn't find any words about subapical cells there...
Yes, it's possible to reach these descriptions on
http://www.delta-.../index.htm (British insects) directly.

I will see where the intkey takes me when sorting this out. :)
