Populus nigra
The larvae feed on "Populus alba", "Populus x canadensis", "Populus nigra", "Populus nigra" cv. 'Italica', "Salix alba", "Salix fragilis", "Salix pentandra" and "Salix purpurea". They mine the leaves of their host plant. They create a lower-surface tentiform mine, usually between two side veins. There is one strong lengthwise fold. The pupa is made in a cocoon. The frass is incorporated in the sides of the cocoon.
