The thoracic dorsum is blackish and shiny, in contrast to the greenish dorsum of most species of Syrphus and Epistrophe. Without long, dense hairs. Scutellum yellow. Wing clear, without dark patch. Face with a black middle line. Frontal lunule black. Hind tibiae with black ring after middle.[3][4][5][6] The male genitalia and larva is figured by Dusek and Laska (1967).[7]

Then European Russia and the Russian Far East, Siberia to the Pacific coast (Sakhalin and Kunashir islands) Also in the Himalayas (Nepal). In North America from Alaska to Mexico.[8][9][10]
