Egg masses appear as 1.5 inch (4 cm) tan or buff-coloured hairs on tree trunks, outdoor furniture or the sides buildings.
Gypsy moth caterpillars change appearance as they grow. Young caterpillars are black or brown and about ¼ inch (.6 cm) in length. As they grow, bumps develop along their backs along with coarse, black hairs. Each of the 11 sections of a developed caterpillar will have two coloured spots, the first five pairs, blue, and the last six, red. Mature caterpillars can be as long as 2 ½ inches (6.35 cm).
Gypsy moths are seen only in mid-summer. Males are grayish brown and can fly; females are larger, whitish with black marks and cannot fly.
