Identification
Adult sexually dimorphic. Forewing of male blackish-brown with small white patch on inner margin near PM line. Forewing of female similar to Baltimore Bomolocha, but PM line straighter, farther from outer margin, and with one tooth. Orbicular spot a black dot. Female has an apical dash, lacking in male. Some dark brown under blackish-brown median patch. Hindwing dark grayish-brown, darker in male than in female. [adapted from description by Charles Covell]

Range
North America except the arctic (British Columbia to Newfoundland, and all of United States).(2), (3), (4)
Habitat
Forests, old-fields, with hostplant
Season
adults fly from April to September or until frost
Food
Covell states larval food is Red-osier Dogwood, Cornus sericea. (5) They likely have another hostplant, since the adults of this moth have been observed in the lower Piedmont (Durham County) of North Carolina, where C. sericea is not known. Other Cornus species are present in that area: C. florida, C. amomum, C. stricta, and C. alternifolia (rare). See Radford, et al., Manual of the Vascular Flora of the Carolinas.
Handfield reports larvae feeding on Cornus stolonifera = sericea (Red-osier Dogwood) and C. alternifolia (Alternate-leaved Dogwood) in Quebec. Larry Line states larval food as Cornus florida (Flowering Dogwood) in Maryland.
