Life Cycle
provided by University of Alberta Museums
The life cycle usually requires 2 years to complete. Adults emerge around May to June. They will then feed on coniferous foliage and bark until mating occurs. Females will deposit eggs into slits they have chewed into the bark. The larvae will emerge in around 2 weeks and begin feeding. The larvae will overwinter and then make their back to the surface, creating a u-shaped excavation tunnel. They will then pupate near the surface and adults will emerge next spring (Ives and Wong, 1988).
