SeasonalityAlberta specimens have been collected in late June and early July.IdentificationA relatively small broad-winged moth (wingspan (2.4–2.8 cm.), but one of the larger Alberta species of the genus Scopula. The wings and body are light tan, almost white, liberally sprinkled with darker yellow-brown or grey-brown scales, except for the collar, frons, palps and legs, which are darker rusty-brown. Both the fore and hind wings are crossed by faint narrow median and postmedian lines, and even fainter partial antemedian and subterminal lines, in particular on the forewings. All four wings have a small black discal dot. The relatively large size, indistinct markings and discal dots will help separate fuscata from other Alberta Scopula species. The male and female genitalia are described and illustrated by McGuffin (1967).
