A medium size moth (3.7- 4.1 cm wingspan) that comes in both grey and reddish-brown color forms. The forewings have few prominent markings, and are dusted with grey scales giving them a clouded or frosty appearance. The reniform usually stands out against the ground, and there are poorly defined darker markings along the costa and in the terminal area, especially near the apex. The hindwings are white, with a bit of dark shading along the outer margin. The narrow, jet-black thoracic collar will separate exuberans from most similar moths, in particular from Euxoa sp. The related and much more common Anicla tepperi is gray and has prominent dark lines crossing the forewings. Until recently placed in the genus Euagrotis, now sunk as a subgenus under Anicla (Lafontaine 2004). The older literature (i.e. Bowman, 1951) lists it as E. bairdi.
