A survey of Trichoptera (caddisflies) carried out in 1984 and 1985 at Stillfork Swamp, Carroll County, Ohio resulted in a total of 7,974 adults representing nine families, 38 genera, and 104 species. Polycentropus clinei (Milne), Pycnopsyche aglona Ross, and Frenesia difficilis (Walker) represent new state records. Leptoceridae, the largest family, was represented by 25 species and constituted 22.5% of the total collection. The Hydropsychidae, Hydroptilidae, Limnephilidae, and Polycentropodidae included 22, 20, 15, and 13 species respectively. The most abundant genus, himnephilus, was represented by two species, indivisus Walker and submonilifer Walker, both characteristic of temporary lentic waters. Seasonal distribution, species diversity, and trophic structure were evaluated. Shredders, the largest trophic category, constituted 31.7% of the species and 37.8% of the total collection.
