This moth cannot be readily distinguished as an adult from Grey Dagger (
Acronicta psi) except by examination of the genitalia, although in the caterpillar stage this is not a problem as the species are quite different.
The larva feeds on a variety of plants. This species overwinters as a pupa, sometimes spending two winters in this form.
