The wingspan is 38–43 mm. Adults are on wing in August in Alberta. There is one generation per year.

The larvae feed on a wide range of plants. In eastern North America they can become pests on vegetable crops and in some fruit trees, damaging buds and new growth. Recorded food plants include white spruce, walnut, hickories, oak, strawberry, apple, cherry, plum, peach, potato and tomato.

Abagrotis alternata does not have a significant economic impact despite its prevalence in the northern United States.[1]
