Abstract

A 5-year study of Laspeyresia pseudotsugae n. sp. (Lepidoptera: Olethreutidae) yielded considerable data on the habits, life history and immature stages of this insect, which gained attention because of its conspicuous bark-mine scars on the trunks of young Douglas-fir trees, Pseudotsuga menziesii (Mirbel) Franco. The mines are not deep enough to cause serious damage. L. pseudotsugae has a 1-year life-cycle. Three species of ichneumonid parasites were recovered, and several predators were identified.
