Korb-Weide
The larvae feed on "Salix alba", "Salix babylonica", "Salix daphnoides", "Salix fragilis", "Salix incana", "Salix purpurea", "Salix triandra" and "Salix viminalis". They mine the leaves of their host plant. They create a large, lower-surface tentiform mine, generally against the leaf margin and often low in the leaf. The lower epidermis is strongly folded and the mine is strongly contracted, causing the leaf margin to fold over the mine in a tube-like fashion. Pupation takes place in a light brown cocoon without frass, which is instead deposited in a corner of the mine.
