The caddisfly fauna of 14 Ohio remnant bogs and fens was sampled by means of light traps operated from May to October in 1984 and 1985. A total of 37,061 adult Trichoptera representing 13 families, 43 genera, and 135 species resulted from 123 collections. New state records are reported for Glossosoma intermedium Banks, Goera calcarata Banks, Lepidostoma costale (Banks), Limnephilus hyalinus Hagen, and Oecetis ochraceae (Curtis). Detrended correspondence analysis of the 100 most abundant species revealed significant correlations between the ordination axis scores and latitude, longitude, caddisfly species richness, and diversity. Documentation of the Trichoptera of these bogs and fens may provide important baseline data for the evaluation of future environmental changes and the management of Ohio's wetlands.
