Korb-Weide
The larvae feed on "Salix cinerea", "Salix caprea", "Salix aurita", "Salix fragilis" and "Salix viminalis". They mine the leaves of their host plant. The mine consists of a long corridor made in the bark, running up or down and hardly widening. Finally, the corridor enters a petiole and a leaf where, close to the base and at the upper side, a white cocoon is spun in which pupation takes place.
