Life History The adults are nocturnal and come to light. Up to 225 eggs are laid, which hatch in about ten days. The grey brown striped larvae resemble twigs, and overwinter when nearly mature (McGuffin 1981). Conservation Not of concern. Diet Info

Prentice (1963) reports two larval collections from buffaloberry (Sheperdia canadensis) in the Alberta foothills, and one collection on douglas-fir (Pseudotsuga menziesii).

Records of this species at prairie localities where both conifer
