Life Cycle
Eggs are laid in July on needles in upper part of tree and hatch about 10 days later; newly-hatched larvae do not feed and spin small silk shelters (hibernacula) in bark crevices in which they overwinter; in spring of the following year, young larvae feed on staminate flowers, cones, old needles, and bark of twigs; larval development occurs in a shelter composed of foliage of a few twigs connected by loose strands of silk; pupation generally occurs on the same shoot.

Numbers are highest, and outbreaks most common in Ontario, Manitoba, and Saskatchewan.
