Adult: typical color form is yellow and a delicate pink in broad bands--distinctive, along with hooktip shape. Forewing PM line angles back sharply toward costa below apex. Hindwing PM line wavy, sometimes lacking. Form "irrorata" is entirely brown or brownish-purple with dark lines - a leaf mimic.
Larva: orange to brown; head with prominent thorny projection to either side, resembling two horns; third thoracic segment arched; tail with long tapering point, the only eastern caterpillar with the latter feature.
