General Description

A fairly large (3.2-5.8 cm wingspan) broad-winged moth with glistening dark sooty brown forewings and copper-orange hindwings. The forewing basad to the postmedian line is darker than the terminal area. The postmedian line, the orbicular spot and to a lesser degree the antemedian line are light brown to dirty white. The antennae are simple, and the sexes are essentially alike. The large size and shining, coppery-orange unbanded hindwings will separate the Copper Underwing from all other Alberta moths.
