Virgin tiger moths sport dramatic geometric forewings laced with creamy lattice markings that conceal brilliant scarlet, black-spotted hindwings. When disturbed, they flash these vivid underwings to startle visually oriented predators or release foul chemical defenses sequestered during their larval stage. The dark, bristly caterpillars spend the winter dormant beneath damp forest leaf litter, resuming feeding on early spring herbs before spinning loose cocoons.
