This is another insect.

Chrysotoxum festivum, at least if it was in the Central Europe

The Middle Urals is not very close to Central Europe.

Indeed

I have no idea whether there are more species with a black abdomen margin in Russia than in the Central and Northern Europe. Maybe not. I use Russian keys for some insects and I was surprised that it works.

Hello!
Thank you very much for your response to my request.
I read some Russian-language scientific publications on entomology. Chrysotoxum festivum has a body length of 12-15 mm, and the length of our insects is 8-9 mm. This is probably a polymorphism. Is the body length of the insect a key feature for identifying the species Chrysotoxum festivum?
Chrysotoxum festivum is an insect with a multiregional polyzonal habitat. If the European entomologists use other terms, then I ask you to excuse me. Chrysotoxum festivum in the group of insect species with a widespread area in Europe. In Siberia, the range gradually narrows and ends in the Baikal region. At present I have not found exact information about the occurrence of Chrysotoxum festivum in the geographic region (southern part of the Perm Region) in which these insects are photographed. But it is found in the Vologda region. Therefore, there is a high probability that the southern part of the Perm Region is the area of ​​its habitat. In fact, such a method of identification of a biological species is incorrect, since this is a rough interpolation. But, unfortunately, I do not collect insects and do not have the opportunity to provide additional signs for species identification.
With best wishes, Irek!
