Asp or Puss Moth Caterpillar

Megalopyge opercularis


Puss moth caterpillars are teardrop-shaped, and, with their long, silky hairs, resemble a tuft of cotton or fur. Their color varies from yellow or gray to reddish-brown, or a mixture of colors. The mature larva is 1 to 1 1/2 inches long with seven pairs of prolegs (suction-cup like claspers on the rear of the body). The adult moth has blunt wings covered with long, wavy hair and a wingspan of 1 to 1 1/2 inches. Wings are orange at the base, fading to cream-colored at the tips. Among the long body hairs are shorter spines that discharge venom upon contact. The head and legs are not visible from above.
