Thread subject: :: [Choerades marginata - group] Asilidae ID

Andrenosoma atra is quite unlikely. Have a look at the typical Choerades-like terminalia. I think it's a male of the Choerades marginata - group, probably Choerades femorata (Meigen, 1804) because of the white hairs beneath the antennae, the rather long first segment of the antennae und the rather strong femora of the hind legs. Some authors do not separate this species from Ch. dioctriaeformis (Meigen, 1820), some do (compare the identification key for the German robberflies by Fritz Geller-Grimm). There is still a lot of confusion within this species group.
