The adult moths of this species are brown with a stripe across each wing and recurved pointed wingtips. Both sexes are similar in coloration and pattern but the females tend to be a little larger. Male wing span 40 - 45 mm, females up to 50 mm. The antennae of both sexes are threadlike, but the antennae of the female are thinner.
