3 April, Clitheroe England. Guessing from the Gallery, I thought the pre-sutural dcs too strong for Tephrochlamys, so maybe Heteromyza? Help please, Andrzej!

I caught a pair of these (possibly not this pair, as there were several flies together on the birch tree - they seemed to be finding sap), so what should I look for to determine species? Is there an easily available key?

Attach plz, a lateral shot ! and you can also take out the long styli from the male (or separate its from the abdomen).
There are two closely related specie: Heleomyza serrata and Heleomyza captiosa.
See, plz comments at the Diptera.info: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27888.

Heleomyza serrata (L.) Grin
Epandrium rather rounded than narrowed apically (egg-shaped Wink ) and styli rather banana-like than hockey stick-like typical characters for H. serrata !

If the styli are under the slide are better to compare with others,
captiosa is here: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27888 Wink

Indeed, Andrzej, that photo is very clear. Do you have then a similar photo of serrata?

It was a thread few weeks ago about the serrata/captiosa problem:
http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=27392 . The styli are more thickened but enough for comparison

Sorry Ruud, I didn't mean anything like that. I found your questions very relevant, and I should have thanked you too. Please continue if you have more to say Smile

At least I only do it accidentally, Roger Pfft If I hadn't been called away for my tea at the critical moment I'd have been more careful awkward

Is that 'Saint' Roger in the Simon Templar sense?
