Not Cheilosia pagana by chance? In our spring, this is the most common type. And with an orange sawyere. In other things, to climb into the collection and compare at such a late hour laziness, probably as always stupid.

No, the assumption is not bad, I still went to check, it became interesting... Unfortunately, pagana has naked eyes (group A). Here, the photo clearly shows that the eyes are pubescent. Of the secondary features-in pagana, the third segment of the antennae is slightly elongated, not rounded, and the basal segment of the apron of the legs is black or brown, but darker than in the photo. And so - you know better what you have flying there with orange antennae in the spring ))) I can assume: C. latifrons (= intonsa), C. flavipes, C. albipila-this is a key fly, from the usual species, and this is not the whole list

Managed to unearth almost an entire puparium
Empty puparia, from which flies came out, without a lid with horns
[attachmentid ()=172767]
[attachmentid()=172768]
[attachmentid()=172769]
[attachmentid ()=172770]

In fact, despite the different shape (more elongated) and darker integuments, the proportions of the anterior spiracles, as well as the shape and color of the posterior breathing tube (these are two fused posterior spiracles in the form of a tubercle), I think this is analis. In general, only in 2003-2004 were published data and opinions that analis and major are different species, because the morphology of the adult and the structure of the male genitals do not give much reason for this, i.e. the names were considered synonymous. According to Schmid (2004), the puparium analis is usually shorter (maximum 9.0 mm), lighter (from light brown to reddish brown), and the anterior spiracles are cylindrical in shape. In major, the puparium is longer (at least 9.0 mm), darker (blackish-brown), and the spiracles are conical. There are other differences.

Their main difference is in the biology of larvae. It is believed that analis lives in the nests of ants of the genus Lasius, and major - in the nests of Formica. Here, by the way, you have a great opportunity to confirm this opinion or make it doubt its correctness. Flies are very rare in my area, they do not like the steppe zone, otherwise I would have buried myself with my head in anthills

. I only have 1 copy. Microdon mutabilis from my region, but to the north, for example, in the Kharkiv region (there is already a forest steppe), microdones are common...

The color is dark, apparently because it did not die by its own death, the rest of the puparia are lighter. I'll try it out tonight and catch some ants from this log tomorrow

And the larvae can not differ, just because some live in lasiuses, and others in formica, and not because some analyzes, and others majors

I decided to collect in one place all the equal-winged birds shot over several years. Below, the published animal is designated Bolshegolovka rusty. I looked in the Internet, in my opinion, it does not look like what was taken from me. Is it true that the Big Head is rusty, or did I mess up something when recording earlier?

First of all, do not confuse groups of Diptera with Homoptera, or simply flies and mosquitoes with cicadas and aphids

.
Secondly, do not trust the Internet 100%

, here is the topic http://molbiol.ru/forums/index.php?showtopic=195961, there are special forums for different units, there is at least some guarantee.
My opinion is that the photo shows Sicus ferrugineus, although I'm not a specialist

.
PS: and try to write the names in Latin

Dear Evgeny, It is difficult not to agree with the completely fair comments made. You won't believe it, but I can guess who is part of the dipteran group and who is part of the equidistant wing, but after four hours of shooting in the sun, it won't even occur to you. Thank you for the website address. All the best
