The larvae feed on the leaves of "Acer rubrum", "Acer saccharinum", "Acer spicatum", "Quercus rubra", "Betula" (including "Betula papyrifera"), "Corylus" and "Fagus" species. They are light green and reach a length of about 19 mm. Early instar larvae may overwinter in hibernacula on twigs of their host plant. Pupation takes place in a folded leaf shelter.
