Caterpillar Pitch Moth


Adult moths are reddish/orange with silver markings on the wings. The mature larvae are about 0.63 inch long and reddish/brown with black heads. The larvae of the moth feed on the buds. They first bore into needles or base of the bud. Next the larva bores partially into the buds and weaves a small web between the two, and seals it with pine pitch. Eventually the infested buds are covered with what appears to be a glob of pine pitch, but it is hollow. As the bud develops, the injured side cannot grow.
