Abagrotis discoidalis
University of Alberta E.H. Strickland Entomological Museum Read more about this collection »
SeasonalityAlberta adults are on the wing late June through mid-August.
IdentificationOne of the small western species of Abagrotis. Superficially they resembles A. hermina in having dark brown forewings and pale hindwings. However they can be easily separated from other species of Abagrotis by the dark streak passing through the orbicular and reniform spots, and in particular by the black filling in the space between the two spots. Even in poorly marked specimens some evidence of this streak will show. In this character they resemble some species of Euxoa.
