Males patrol in swales most actively in the afternoon, and mating takes place then. Females lay eggs singly on leaf buds and tops of leaves. Adults roost exposed on a tall plant beginning in late afternoon. Caterpillars make folded-leaf nests in which they live and feed, and fully-grown caterpillars hibernate.
