September 20. Helophilus pendulus ??

Please identify this copy. 27.09.2012г. Rostov region.

Show off, perhaps Mottledwing from the genus Terellia

Thank you very much! It looks
like Terellia
longicauda is the same species in item 2 of my post

Why not T. serratulae, for example?

As far as I understand, without spots on the wings - one kind. And it was taken on the same plant as most of the posted photos. Therefore, I assumed that T. serratulae also has spots on the wings. Of course, the approach is not scientific, but I can do it as best I can...

No, there many species have transparent wings, serratulae have no spots on the wings, it is longicauda that has implicit darkening: http://www.diptera.info/forum/viewthread.php?thread_id=49253
It would be better, of course, to fix and look honestly at the keys.

3draw us! Can you help me with the flies and the pusher?

Unfortunately, I don't know the shooting dates. Filmed in Belarus.

Please help me identify the remaining sirfids(hopefully there will be more this year ) All from Moscow and the Moscow region.

2. 29.07

3. 12.08 E.tenax?

4. 4.08 E.tenax?

5. 12.08 E.arbustorum?

6. 1.09 H.pendulus?

7. 16.08

8. 17.08

9. 17.08

Thank you in advance!

Hurray! I found another sirfid!



Moscow region, Pushkinsky district, 8.08. Melanostoma mellinum?

And what kind is needed for a more accurate definition?

Please identify two copies. On tansy. 01.10.12 Rostov region.

Face with high magnification and quality: it is necessary to look at the development of a light coating and pubescence of the arista (thin antennae at the end of the antennae), M. mellinum has no plaque and pubescence (and this female, it seems, has a "powdered"face).

Oh, I'll go to the flies someday...

1-male Sphaerophoria seems to be scripta

Will that help?

Thanks! Here's another one: the label is the same.

Thanks!
