The Douglas-fir tussock moth, Orgyia pseudotsugata (McDunnough), is an important defoliator of spruce, Douglas-fir, true fir and other conifers in the Rocky Mountain region.

Feeding by the larvae can cause complete defoliation of heavily infested trees. Damage usually appears first in the tops of trees and progresses downward, sometimes over several years.
