Distribution Scandinavia, East Prussia with the Baltic to northern Russia, the Alpine region, Carpathians (De Friena & Witt, 1990)
Habitat Principally moist meadows. In the Alps they occur in meadows from about 1800 m to above the tree line about 2,600 m (De Friena & Witt, 1990)
Biology Univoltine. Emergence between July and September. Moths fly at dawn (oscillating flight) and then rest during the day, although males occasionally fly during afternoon sunshine (De Friena & Witt, 1990). Before pupation the caterpillar resides about 10 cm below the ground in a perpendicular silk lined tunnel within which the pupa can move up and down. Following emergence of the moth the exuviae are left projecting a few centimeters from the ground (Rudolf Bryner)
Conservation threat level The species is localized, but not rare in its habitat (De Friena & Witt, 1990)
