Book excerpt: Excerpt from Douglas Fir Tussock Moth Egg Hatch and Larval Development in Relation to Phenology of Grand Fir and Douglas-Fir in Northeastern Oregon Bud burst, shoot elongation, egg hatch, and larval development were studied on six areas in a 1973 infestation in the Blue Moun tains.

Larval development then closely followed shoot elongation. This synchrony of host and insect phenology provides an easily observed field event for monitoring Douglas fir tussock moth development.
