The wingspan is 35–45 mm. The moth flies from May to July; the larvae remain from July to September.[1] There is one generation per year. The larvae go through five instars; the final instar is black at the ends, with a yellow or orange middle section, which in some populations has black spots.[2]

The larvae feed on the leaves of poplar and willow, but also feed on alder, basswood, birch, maple and oak.

It is a tiger moth but is commonly referred to as a "tussock moth" for the tufts of hair on the caterpillar. According to Wiktionary, a tussock is a tuft or clump of green grass or similar verdure, forming a small hillock.[1]
