Walnut Caterpillars


Walnut caterpillar moths are light brown with four narrow, brown bands on each front wing and a dark red brown thorax. The wingspan is about 1 3/4 inches. The larvae are dark red when young but become black near maturity. They have many long, white hairs on the body. When disturbed, they usually raise the front and back thirds of the body. Mature larvae are about 2 inches long.
