Known for its graceful flight and bright orange coloration. The upper side of the wings is a striking orange with black markings, particularly near the tips of the forewings. The underside is a pale brown or tan, with faint orange markings, providing camouflage when at rest. Frequently seen feeding on Mexican Sunflowers.
