Forewing is pointed, particularly in the male. Males perch to watch for receptive females. Eggs are deposited on or near the host.
Caterpillars feed on grass leaves and live in silken tubes at the base of grass clumps.
They overwinter in shelters that are partially buried. Two broods from May-September with a longer flight period in Florida. Nectar from flowers of prickly pear cactus, alfalfa, thistles, and purple coneflower. Short-grass prairies, pine barrens, and woodland meadows. A separate population occurs from central Kansas south to east-central Texas.
