Looks like divaricatus, but I need to check the wing pattern

Chrysops divaricatus?
I read that this is a rare species of an insect.
I was lucky :)

I don’t know what you read, but read Olsufjev (1977). divaricatus is common in northern Europe and western Siberia.

This is a misunderstanding because of problems with my English ...
I meant the low abundance of the species.
Pestov SV, Dolgin MM. Tabanid fly (Diptera, Tabanidae). - SPb .:, 2013. 190 pp. (Fauna of the European Northeast of Russia, Tabanid fly, T. XI, part 1) on page 37 about Chysops divaricatus the following is given. Quote:
Sporadically occurs only in the southern and middle taiga. Relative abundance is less than 1%.
On page 170 for the southern taiga is given with an abundance grade of 1 rank (low abundance of the species), for the middle taiga with a grade of 3 ranks (common species).
According to the finds, 1-2 individuals are found in different places of collection. For the North, Chrysops diviricatus is an insect with a low relative abundance.
