Northeast and mid-Atlantic states from Nova Scotia in the north to South Carolina in the south. The species is known from as far west as western Pennsylvania and western North Carolina. (1)
The similar species of Leucania inermis-ursula-pseudargyria species complex cannot be identified with certainty except by dissecting the male genitalia. (1)
Leucania pseudargyria - usually the easiest of the four species to recognize because of its larger size and the red tint to the forewings usually (but not always) present.
Leucania ursula - slightly smaller then similar inermis. Both species are always gray without the red tints that are present in the larger pseudargyia.
