The wingspan is 25–32 mm. The moth flies all year round in the south and west and from April to November in the northeast. There are two generations per year northward over most of the east.

The larva, or hop worm, is about an inch long when full grown, of a greenish-white color, watery looking or semi transparent, and slightly striped and dotted, having fourteen legs. The mouth is yellowish, and the tips of the jaws black. The larvae appear early in June, and continue until late in August.^[1] They feed on Laportea species, hop, nettle and wood nettle.
