Lithomoia germana
American Brindle, American Brindle Moth
Lithomoia germana, commonly known as the American Brindle, is a noctuid moth with a broad distribution across northern North America. Adults are bivoltine, active in spring and again in late summer to early autumn. The species is notable for hibernating as an adult, an overwintering strategy that allows early spring emergence. Larvae feed on woody plants in Salicaceae and Betulaceae, while adults visit goldenrod flowers for nectar.
Polygonia
comma, anglewing
Polygonia is a genus of butterflies in the family Nymphalidae, commonly known as commas or anglewings. Members are recognized by a conspicuous white comma-shaped mark on the underside of each hindwing and angular notches on the outer edges of the forewings. The genus exhibits remarkable seasonal polyphenism, with distinct light and dark morphs corresponding to non-diapausing and diapausing generations. Many species hibernate as adults. The genus has been alternatively classified as a subgenus of Nymphalis.
