Identification
Two forms: typical form is all dark brown like Tissue Moth (Triphosa haesitata); form "badiaria" has orangish-brown AM and ST bands; both forms have a sharper forewing apex than Tissue Moth, and a more jagged PM line with an especially prominent "tooth" near the costa; forewing not blotched brown, as it is in Tissue Moth
hindwing pale grayish-brown with variably distinct lines
Range
all of United States and southern Canada
Season
adults fly May-October; several broods
Food
Larvae feed on Barberry (Berberis). This is an introduced shrub in most of Eastern North America--the native American Barberry (Berberis canadensis), is rare in the Southeast.
Life Cycle
several generations per year in the south; fewer in the north
See Also
