Males have square grey dust spots each side of tergites 2 to 5. See Schmid, U. (2000) for certain determination^[1]^[2]^[3]^[4] The larva is described and figured by Rotheray (1994).^[5]

Distribution

Norway and Finland South to northern France. From Ireland East across mountains of Central Europe, Roumania and Bulgaria. ^[6]^[7]
