A small (approx. 2.0 cm wingspan) moth with whitish or pale grey squared forewings and grey hindwings. Forewing markings variable, with dark grey or rust markings indicating the inverse costal triangle – usually reduced to dark spots on the costa and in particular the dark discal dash at the apex of the "triangle". A few small spots or dots of the same color elsewhere on the forewings, in particular in the basal area. There is a series of raised white scales that form an inverse arc across the forewings when forewings when at rest. The dirty white or pale grey forewings with the few dark markings on the forewing will help distinguish this little moth.

Larvae are solitary leaf-rollers. The primary hosts are birches (Betula); also recorded from Viburnum and alder (Alnus). Adults in fall (late Aug. – early Oct.) and again in spring (mid Apr. – early June), apparently hibernating. Adults come to light.
