The Western Blackheaded Budworm (Acleris gloverana) is a moth of the Tortricidae family. It is found in Alaska, British Columbia and Oregon. The larvae feed on Tsuga heterophylla, Tsuga mertensiana and Abies species. The species is considered a pest. Severe outbreaks, which occurred on the coast during the 1940s and 1950s covered millions of acres and resulted in considerable tree mortality. Since that time, outbreaks have occurred in the interior from 1965 to 1968 and on Vancouver Island from 1970 to 1973. Tortricidae is a family of moths in the order Lepidoptera. They are commonly known as tortrix moths. It is a large family with over 9,400 species described, and is the sole member of the superfamily Tortricoidea. Many of these are economically important pests. Olethreutidae is a junior synonym. The typical resting posture is with the wings folded back producing a rather rounded profile.
