Isoperla francesca Harper 1971

Isoperla francesca Harper, 1971 Notes Isoperla francesca is commonly known as the Northeastern Stripetail (Stark et al. 2012). This species has been reported infrequently in northeastern North America, with records available from Nova Scotia east to Quebec and southwest to Pennsylvania (Szczytko and Kondratieff 2015, DeWalt et al. 2024). Harper et al. (1991 b) suggested a univoltine-slow life cycle for this species in Quebec. We report an adult flight period in New York from mid-May through late July (Fig. 38). Populations of I. francesca have been documented at elevations ranging from 203-620 m asl (Fig. 39) from a broad range of stream sizes from Level IV Ecoregions Adirondack High Peaks (58 z), Acid Sensitive Adirondacks (58 aa), Northern and Western Adirondack Foothills (58 ab), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad), Tug Hill Plateau (58 ae), and Upper St. Lawrence Valley (83 e) (Fig. 41 d).
