Abstract

This report was prepared to facilitate the separation and identification of lepidopterous larvae associated with the spruce budworm (Choristoneura fumiferana (Clem.)) in its various feeding sites on spruce (Picea spp.) and fir (Abies spp.) in northeastern North America. Three dichotomous keys, with 12 illustrations, are presented; they deal with needleminers, defoliators, and cone feeders. Twenty-two references to the larval morphology and/or biology of species are cited.
