A species of Chalcosyrphus. I will leave it to the true specialists to decide whether this is C. femoratus (= curvipes sensu auct.) or C. valgus (= femoratus sensu auct.[/i]).

See: http://home.hccne...y_key.html.

Thank you Paul.
So, in old key it is still in Xylota genus.
I looked at fly (collected) - "apex of the hind tibia extended ventrally into a large triangular flange", so my test it is Chalcosyrphus femoratus. And I think that size is realy more 14-15mm.
