Adults' bodies are 20–26 millimetres (0.79–1.02 in) in length and blue, with red heads and shoulder markings.[3] The length of the forewings is 18–20 millimetres (0.71–0.79 in). Adults are on wing from mid May to mid July. They feed on the nectar of Heteromeles arbutifolia.[4]
Eggs are round and fade from white to yellow, and laid in rows. The larvae are black with buff-colored or yellow hairs, with two black tufts on the front and rear and an amber or orange head.[4][3] They feed on Leymus condensatus and other grasses and sedges.[5][3] The pupae are chestnut in color and wrapped loosely in a cocoon of the larval hairs.[6]
