Orgyia definita, the definite tussock moth or definite-marked tussock moth, is a moth of the family Erebidae. It was first described by Alpheus Spring Packard in 1865.[1] The species is found in eastern North America from Minnesota to New Brunswick and south to South Carolina, Mississippi, and Louisiana.[2][1]

The wingspan is about 30 mm for males; females are wingless. Adult males are brown with a darker pattern and some white markings.

The larvae feed on Salix, Quercus, Tilia, Ulmus, Betula, Acer rubrum, and Hamamelis virginiana. They have a yellow head, prothoracic plate and dorsal glands. The body is covered in whitish hairs and the verrucae (wart-like structures on the body) are pale yellow.
