Phylogenetic sequence # 931200 (1)
Covell (1984) listed the wingspan 3.8-4.0 cm. (2)
Adults - forewing yellowish to pinkish-brown with dark brown shading and subterminal line; stigma consists of nearly solid inner part shaped "like a G or chemist's retort" (2), usually separate from solid outer part in eastern specimens, but often joined in western specimens; small inconspicuous white ring often present in median area near costa; metallic brown patch over center of ST line; bottoms of AM and PM lines gold and black
hindwing grayish-brown with darker distal half and pale median line; antenna simple; sexes similar.
Newfoundland to North Carolina, southwest to New Mexico, north to British Columbia and Northwest Territories.
Open woodland, clearings and edges, hay meadows, fields; adults are nocturnal and attracted to light.
Covell (1984) reported July and August. (2)
Larvae feed on common dandelion Taraxacum officinale (Tietz, 1972), and have been reared on plantain (Plantago spp.) and Stinging Nettle (Urtica dioica).
Life Cycle
One generation per year.

In British Columbia where both species occur, Autographa speciosa has a similar stigma, but the forewing of that species has several pale gray or whitish areas
Elsewhere, the stigma shape of A. bimaculata is diagnostic.
