The wing length is 9 ·75-11·5 mm.

Male tergite 4 with front edge of wedge-shaped bars clearly separated from the front margin of the tergite or just touching front of tergite on median line. [4] [5] [6] The male genitalia and the larva are figured by Dusek and Laska (1967) . [7]
A Palearctic species with a wide distribution in Europe and East across Russia to the Pacific coast, Mongolia, Japan and Korea. [8] [9] in North America from Alaska south to Colorado. [10]
Habitat forest; conifer forest and taiga, Quercus woodland. [11] Arboreal, descending to visit flowers of white umbellifers, yellow composites, Cirsium, Plantago, Potentilla, Rosa, Rubus idaeus, Salix, Sambucus ebulus, Valeriana officinalis, Viburnum opulus. [12] The flight period is mid May to early September. The larva is arboreal and feeds on aphids associated with Larix, Prunus, Salix and Quercus.
