Abstract

The family Perlodidae is one of the most abundant and widespread in the order Plecoptera. These stoneflies occur in a wide variety of clean-water habitats and as indicator organisms have potential for assessing water quality. Studies of this family in Wisconsin prior to 1965 were limited to occasional collections reported by Needham and Claassen (1925) and Frison (1935, 1937, 1942). In 1965 and 1966 a survey of the Wisconsin River and its tributaries yielded nymphs of 11 species of Isoperla (W. Hisenhoff, unpublished report), and later, nymphs and adults of 9 species were found in the Pine-Popple River (Hilsenhoff and Narf 1972). Between 1966 and 1971 additional Perlodidae were collected throughout the state by several persons, many of them by Arvin Krueger while surveying the mayfly fauna of Wisconsin (Krueger 1969).
