Abstract.— The Femow Experimental Forest is a research facility of the U.S. Forest Service located on the Allegheny Plateau in the northern part of Monongahela National Forest in Tucker Co., WV. This 1474-ha experimental forest encompasses the entire drainage of Elklick Run, a 4th order tributary to the Black Fork of the Cheat River. As part of several ongoing studies of the ecology of streams in the Femow Experimental Forest, we conducted a survey of adult aquatic insects in 6 of these small catchments. From this survey, we identified 27 species of Plecoptera including 1 species of Pteronarcyi-dae, 1 of Peltoperlidae, 1 of Taeniopterygidae, 2 of Capniidae, 7 of Leuctridae, 4 of Nemouridae, 5 of Chloroperlidae, 1 of Perlidae, and 5 of Perlodidae. Key Words: Plecoptera, species list, Femow Experimental Forest, West Virginia The Femow Experimental Forest is one of several experimental forest areas oper-ated by the Northeastern Forest Experiment Station of the U.S. Forest Service for catch-ment-level research in forestry and water-shed management. It is 5 km south of Par-sons in Tucker County, West Virginia in the northern part of Monongahela National Forest (39°3'N, 79°40'W) (Fig. 1). Estab-lished in 1951, the 1474-ha experimental forest is in the Allegheny Plateau Province of the central Appalachians (Aubertin and Patric 1974) and includes the entire catch-ment of Elklick Run, a 4th order tributary of the Black Fork of the Cheat River. The experimental forest includes 9 gauged ex-perimental catchments and several un-gauged catchments (Fig. 1). ' The Unit is jointly sponsored by the West Virginia Department of Natural Resources, West Virginia Uni-versity, the U.S. Fish and Wildlife Service, and the Wildlife Management Institute. Our research in the Femow Experimental Forest on the effects of acid precipitation and the nontarget effects of the application of the forest pesticide, diflubenzuron, has included work on the macroinvertebrate communities of the 2nd order streams that drain several of these headwater catchments (Griffith and Perry 1991). Only two previ-ous studies have produced surveys of streams in the Femow Experimental Forest. Case ( 1983) collected kick samples of aquat-ic nymphs from Watersheds 1, 4, and 6 and three catchments outside the experimental forest. Harris (1973) collected adults with emergence traps and nymphs with an Eck-man dredge from the weir ponds of Water-sheds 1, 3, 4, 6, and 7. Both studies iden-tified the insects primarily to genus. Also, little collecting has been done by other ac-tive Plecoptera researchers in this part of West Virginia (R. Kirchner, pers. comm.). To facilitate ongoing research at the Fer-
