Identification of Diptera (flies, mosquitoes, etc.)

DSC_1522 Xylota curvipes (The old Chalcosyrphus femoratus is now called Chalcosyrphus curvipes. http://www.diptera.info/forum/viewthread.p...hread_id=21988)

What about the link? The browser doesn't open...

*************
That's it, I opened it - the parenthesis got stuck in the link

So Chalcosyrphus valgus = Chalcosyrphus femorata = Xylota curvipes?

Has anyone seen such a humpback by any chance? On Diptera.info they don't say anything. August 22, In Karelia. They swarmed around the oak leaves, seeming to lick up the sweet sticky sap. Quite large, about 3 mm.

Ukraine, Rivne region.
Eristalis arbustorum, Eristalis interrupta ?

Yes, almost 100%.

Ow!!!!

Another batch of sirfidocs. All from Moscow and the region.
Thank you in advance!

That is, the first is Eristalis arbustorum, and the second is Eristalis interrupta ?
I can't tell the difference between them. Dark little rectangles (trapezoids) on the outside of the wings ?
Is this photo also Eristalis arbustorum ?

Please help me classify the insect. The picture was taken in June, Moscow region. Is this Syrphus ribesii?

Is it possible to classify an insect based on its appearance in the image? The photo was taken in June in the Rostov region. Thank you.

To You here.

Very beautiful and heartfelt photos! The latter - well, absolutely beyond the pressure of cosmogonic spirituality.

Kostya, here is a photo:


This is still Ch. valgus, as far as I can tell (the angle is pretty good). There are three similar types: Ch. valgus (= Ch. femoratus auct., = Xylota femorata auct.), Ch. femoratus (= Ch. curvipes auct.) и Ch. rufipes. In Ch. femoratus, the hind legs are more curved, and a different shape of the black spot on the top of the hind thighs (it is more extensive). Ch. rufipes, unlike the closely related Ch. valgus, has an almost black arista. Other signs are either not visible in the photo, or less significant. Ku!

Meliscaeva auricollis ??

Check out my "flies"
MO, Railway

2. Yes, it is pellucens.
6,9. I do not know ulidiidae, but I would say that it is Myennis octopunctata.
8. Female Eupeodes sp.
14. Female Eristalis sp., possibly E. tenax.

could you please omit the other "flies" below in the taxa or correct my assumptions
1. Calliphoridae
3. Tachinidae, I think Tachina
4. Bombyliidae, Hemipenthes
5,7. Sarcophaginae
10. perhaps Drosophilidae
11. fig knows what it is, stupidly assume Bombyliidae
12, 13 in addition to the fact that Tipuloidea can not assume anything

Melanostoma mellinum, male.

could you omit the rest of the "flies" below in the taxa or correct my assumptions
11. fig knows what it is, stupidly assume Bombyliidae

Thank you so much !!!
And then you were gone for a long time , I uploaded it to the Dipter - they suggested Platycheirus, I assumed Platycheirus scutatus.

I'll assume Therevidae :
