Identification
The can be distinguished from other Acronicta by its combination of small size (wingspan ~32 mm), north-eastern North American distribution, and period from May to August. Accurate identification to species level typically requires examination of genitalia or molecular analysis, as many Acronicta species are superficially similar.
