The forewing has 1 submarginal eyespot, a jagged row of white spots, and the cell has 1 solid black bar and 2 separate black spots.

Eggs are laid in clusters, and the young caterpillars feed communally. Caterpillars overwinter in groups gathered inside dead rolled leaves. The wingspan is about 2-1/2 inches.
