Wings are dark brown-black.
Forewing has a wide yellow band, and a small white patch near the apex. To seek females, males perch in gullies on rocks or up to 6 feet above ground on vegetation. Females lay eggs in strings of 2-7 at the base of host plant leaflets. Caterpillars live in shelters of rolled or tied leaves and emerge at night to feed on leaves. One brood from June-September in southern Arizona.
