The wingspan is 7–9 millimetres (0.28–0.35 in).The head is whitish, mixed with fuscous, face white. Antennae with apex white. Forewings are golden-ochreous; a white median streak from base to 1/3 an ill-defined white dorsal spot at 1/4; a slightly bent median fascia, three posterior costal and two dorsal spots white, anteriorly dark-margined; a black apical dot; dark line of cilia nearly obsolete. Hindwings are grey.[2]

There are two generations per year with adults on wing in late May and June and again in August.[3]

The larvae feed on Salix aurita, Salix caprea and Salix cinerea. They mine the leaves of their host plant. They create a large, lower-surface tentiform mine, mostly between two side veins. The upperside is strongly inflated and the underside has many narrow folds. The pupa is light brown and made in a golden cocoon. The frass is deposited in a corner of the mine.[4]
