SeasonalityAdults have been collected in Alberta from mid-July through mid-August. IdentificationA rather large (3.2-4.2 cm wingspan) bright yellow moth with red-brown markings. The forewings are yellow with a large spot-like basal dash, a large spot midway along the lower margin, and a dark terminal band, all reddish-brown.

Life History Adults are nocturnal and come to light. There is a single brood each year, with adults flying in late summer. Like the other members of the subfamily, the larvae feed on the flowers and seeds of their host plants. Conservation Uncommon to rare at the northwestern edge of their range in Alberta. Diet Info No Alberta data. Larvae have been found on the sunflower Helianthus microcephalus in Ohio (Poole, 1995), and native sunflowers are the probable host in Alberta. Range Northern Florida north to Virginia and southern Ohio, west to southern Saskatchewan and Alberta, Wyoming, Colorado and west Texas. In Alberta it has been collected from Lethbridge north and east to the Wainwright dunes.
