Abagrotis brunneipennis (Grt.)

Abagrotis brunneipennis is found from Newfoundland west to Vancouver Island, south to west central Oregon, Utah, Colorado and North Carolina. In Alberta it has been collected sparingly throughout the boreal forest, from Redwater north almost to Lake Athabasca and in the foothills near Kananaskis.

A medium-size (3.3-3.7 cm wingspan) moth with brick-red forewings and black hindwings. The forewings vary in color in the same population from dull brown with rather prominent dark orbicular and reniform to deep brick red with black basal and subterminal bands (illustrated). The banded form of brunneipennis is unmistakable. Most brunneipennis have a deeper more saturated almost greasy-looking appearance. The markings on most specimens are faint or obsolete, with the dark shade at the top of the subterminal shade most prominent. They are very closely related and most likely to be confused with A. cupida, most specimens of which are lighter orange-red and have lighter black hindwings. Brunneipennis is associated with sandy habitats in the cooler boreal forest and foothills regions, while cupida frequents dry often clay habitats south of the boreal forests. Although bar-code sequence fails to differentiate between cupida and brunneipennis, there are significant differences in both the male and female genitalia. Lafontaine (1998) illustrates the various forms of adults and genitalia of both sexes.

It is found in sandy habitats in association with blueberry.

Adults are nocturnal and come to both light and sugar bait. There is a single annual brood with adults in August and early September.

Wild larvae have been collected on blueberry (Vaccinium sp.)

Abagrotis brunneipennis, the Yankee dart, is a moth of the family Noctuidae. The species was first described by Augustus Radcliffe Grote in 1875. It is found in North America from Newfoundland west to Vancouver Island, south to west central Oregon, Utah, Colorado and North Carolina.

The wingspan is 33–37 mm (1.3–1.5 in). Adults are on wing in August to September in one generation.

The larvae feed on various woody plants, including Vaccinium. They also feed on fallen leaves during the winter.
