The larvae of this moth feed on plants of the genus Populus, which includes Populus balsamifera, Populus tremuloides, and Populus grandidentata, and plants of the genus Salix, which includes Salix alba, Salix arbusculoides, Salix babylonica, Salix bebbiana, Salix brachycarpa, Salix exigua, Salix glauca, Salix integra, Salix interior, Salix lasiandra, Salix longifolia, Salix monticola, Salix novae-angliae, Salix planifolia, and Salix scouleriana. Larvae create mines inside the leaves of their host plants to feed.
