Upperside is brown. Females lay eggs singly on leaf buds or on upperside of host plant leaves.
Caterpillars are solitary and eat leaves.
Caterpillars and adults overwinter but only in the south. Two to three broods from May-October, throughout the year in the Deep South. Dogbane, peppermint, and other flowers are also visited. Open, sunny areas with low vegetation and some bare ground. Adults from the south's first brood migrate north in late spring and summer to temporarily colonize most of the United States and parts of southern Canada.
