SeasonalityAdults have been collected in Alberta in early August.
IdentificationA medium-size (3.4-3.6 cm wingspan) dull grey-brown or reddish-brown moth with few markings. They have a narrow, black prothoracic collar. The forewings are light grey, heavily dusted with dark blackish-brown or red-brown scales, heaviest along the leading half of the wing and giving it a blurred appearance. The antemedian and postmedian lines are visible but poorly defined, as is a blotch-like reniform spot. There is also a narrow dark band on the terminal area. The hindwings are dirty pearl white, slightly dusted with dark scales toward the margin and along the veins, and with a dark discal spot. Females slightly darker. Male antennae biserrate and bifasiculate.
