Identification
Adult: wings smooth purplish-gray, tan, or dark chestnut brown with yellow on median. The combination of black spots at tip of forewing and deeply serrated hindwing is a distinguishing feature of this species.

Genitalia:

♂
Range
Eastern two-thirds of North America (US and southern Canada east of the Rockies). (1)
Habitat
Mixedwood forests
Season
Adults fly from April to September (only June and July in the north).
Food
Larvae feed on roses and Impatiens.
Life Cycle
Up to 230 eggs are laid, hatching in only three to four days; overwinters as larva, likely in the fifth instar. [McGuffin 1981]
