The wingspan is 7 mm. The head is ochreous-yellow with a whitish collar. The antennal eyecaps are also whitish. Forewings dark fuscous ; a small costal spot before middle, and a larger dorsal spot before the tornus whitish ; outer half of cilia whitish. Hindwings grey.[1]

Adults are on wing from May to June. It is a parthenogenetic species, with males being extremely rare.

The larvae feed on Populus tremula and Populus tremuloides (ssp. downesi). They mine the leaves of their host plant. It first bores in the petiole, resulting in a swelling. When the larva reaches the leaf disc, it makes an elongate blotch between the midrib and the first lateral vein. The frass is concentrated in two stripes parallel to the sides of the mine. Pupation takes place outside of the mine.
