Did You Know…
Males perch in valleys or patrol near host plants for females. Eggs are laid in groups on the underside of host plant leaves. Caterpillars feed together when young, sometimes in a slight silk web. Partially-grown caterpillars overwinter. This is a butterfly with highly variable markings showing regional and gender differences. The pattern on the underside of the hindwing is usually sufficient to separate it from similar species.
