The Aholibah Underwing is a moth of the "owlet" family Noctuidae, which has over 25,000 known members, and more than that yet undescribed. Like other moths of Underwing genus (Catocala), this species has dull gray and black speckled forewings which help it blend into its surroundings, and bright orange underwings that it reveals to startle predators.
An adult has a wingspan of up to 8 centimeters. The larva is a dark gray mottled caterpillar with thick pink-tinted legs and a jumping ability. The adults feed on nectar, sap, and rotting fruit, while the larvae prefer the foliage of several oak species.
