features

butterfly

The male moths have a wingspan of about 30 millimeters. The basic color of the upper side of the forewing is predominantly gray, the discal region is red-brown to black-brown. Ring and kidney flaws stand out in ocher color. The cone blemish is long and narrow and also ocher in color. In the suibmarginal region there is a row of black-brown arrow spots, in the basal region a black root welt. The underside of the hind wing is unmarked light gray, darkened to gray-brown towards the edge. The antennae in the males have short sawtooth-like eyelashes on both sides. The thorax is furry red-brown hairy. The almost flightless females only have pointed wing stubs that show similar, but sometimes paler, drawings as the males. They have a plump body shape and reddish brown hair.

Pre-imaginal stages

The first stands have not yet been described.

distribution and habitat

The species is found in Alaska , Yukon and northeast Siberia . She is also on the Bering Sea lying Pribilof Islands , the St. Lawrence Island and on some islands of the Aleutian Islands home. The main habitat are dry or wet tundra-like areas.

Way of life

The moths are diurnal. They were found in June and July. Because of their stubby wings, females move awkwardly in the vegetation or on foot over short distances. Since the species occurs predominantly in areas that are only sparsely populated and remote by humans, no detailed knowledge of their way of life is yet available.
