Adults have a wing span of about 3/4 of an inch. The front wings are tan on the front third and reddish-brown with a coppery luster on the back two-thirds. The mature larva is about 1/2 inch long and a dirty white color with a sometimes greenish or pinkish tint. They can be mistaken for clothes moths. They normally only live for 2 or 3 weeks and are night fliers.
