We examined the abundance, life history, and production of the stonefliesPeltoperla arcuataandTallaperla maria(Plecoptera: Peltoperlidae) in four forested headwater streams at the Fernow Experimental Forest, Tucker County, West Virginia.Peltoperla arcuatawas most abundant in the smallest watersheds (<100 ha), and was present at all sites.Tallaperla mariawas most abundant in watersheds >200 hectares (ha), was restricted to sites with a base-flow alkalinity of >2 mg L-1CaCO3, and was the dominant peltoperlid only at sites with an alkalinity >15 mg L-1. We conclude that water chemistry overrides stream size as a determinant of species-specific distribution of Fernow peltoperlids. Both taxa had semi-voltine life cycles with an 18-month naiadal period following a 6-month egg diapause. Emergence was during May-July for both species.Peltoperla arcuatahad about 15 instars;T. mariahad about 14 instars. Peltoperlid production was highest (509 mg m-2y-1) in a 128 ha watershed where onlyP. arcuatawas collected;P. arcuataproduction was lowest (17 mg m-2y-1) in a 4th order stream (1536 ha).Taltaperla mariaproduction was highest (271 m-2y-1) in a 257 ha watershed partially underlain by limestone. Production across streams was higher forP. arcuata(205 mg m-2y-1) than forT. maria(91 mg m-2y-1).
