Abstract

Adult Trichoptera of 39 species representing 11 families were collected from 4 emergence traps in Oak Creek, Corvallis, Ore., between May 1968 and December 1970. Glossosomatidae and Limnephilidae were the most abundant families, but Rhyacophilidae was represented by the most species. Relative abundance, seasonal occurrence, sex ratios, and ecological segregation of related species are discussed.
