Coloration highly variable ranging from almost white to dark gray; lateral tussocks often composed almost entirely of white setae. Very similar to yellow-based tussock moth but differing in that lateral tussocks below abdominal spiracles bear 1 to few long, clubshaped dark hairs. Dorsal defensive glands reddish. Food: especially willows and poplars, but also oaks, birches, and other forest trees. Caterpillar: September to June; 1 generation.
