The length of the forewings is 4.5–5.7 mm. The forewings are purplish-black with two incomplete thin white bands. The antennae of the males are at least twice as long as the wings. The hindwings are uniformly dark. Adults are on wing from mid April to mid July.
The larvae feed on buds of Holodiscus discolor. Full-grown larvae overwinter in cases on the ground. Pupation takes place in late March or April.
