Tussock moth larvae are very distinctive caterpillars. They have a pair of pencil-like hair tufts at the anterior end, a single similar tuft at the posterior end, and 4 short thick hair tufts on the back. Adult male tussock moths are grayish brown, with broad wings and a wingspread of 20-25 mm.; females are wingless. The Gypsy Moth (PI. 12), Porthetria dispar (Linn.), a species introduced from Europe, is most common in the East; its larva often does a great deal of damage to forest trees. Male Gypsy Moths are brownish, with plumose antennae, and are good fliers; females, white with black markings, do not fly.
