The wingspan is about 12 mm. The forewings are dull ochreous fuscous spotted with black, with a small black sub-costal dot at the base of the wing. There is a small black dash from the basal third of the costa, below and beyond this and occupying about the middle of the cell is a broad ill-defined patch of blackish scales. There is a more or less obscure shading of black scales on the middle of the costa, as well as a black dash just before the apical third of the costa, and below it, extending to the dorsum, an irregular, ill-defined black line. A faint dusting of black scales is found near the outer margin of the wing. The hindwings are very pale, semi-transparent whitish-fuscous.^[4]

The larvae are leaf-tiers on Acer negundo and Acer saccharum.
