AppearanceThe forewing is dark brown with a tan stripe which extends from the base to the apex. There are also white lines that cover the veins. The black hind wing has a broad pink median band. It has a wingspan of 2 to 3 inches. The moth is sometimes referred to as a ''hummingbird moth'' because of its similarity to the hummingbird in appearance and flight characteristics.
BehaviorThe larva is yellow and black or sometimes lime green and black. Many individuals have a subdorsal stripe. The head, prothoracic shield, and the anal plate are one color either green or orange with small black dots. The horn varies from either yellow or orange and sometimes has a black tip.
