The wings of the females have a cloudy yellow-brown color, those of the males are darker brown. A few irregularly arranged black spots are distributed over the wing surfaces, which in some specimens form bands that are similar to transverse lines. The speckled pattern is more pronounced on the outer and front edges. The antennae of the males are double combed, those of the females are darkly ringed with only hinted comb teeth. The thorax is furry hairy in both sexes.

Adult caterpillars are colored black-gray. On the entire length of the body they are provided with black warts from which black-brown tufts of hair protrude.
