Salix viminalis
The larvae feed on "Populus alba", "Populus nigra", "Salix alba", "Salix babylonica", "Salix fragilis", "Salix lanata", "Salix pentandra", "Salix purpurea", "Salix x sepulcralis", "Salix triandra" and "Salix viminalis". They mine the leaves of their host plant. They create a large, lower-surface tentiform mine with one sharp fold. Pupation takes place within the mine in a cocoon. The frass is deposited in the opposite corner of the mine.
