Isoperla bilineata

Isoperla bilineata (Say, 1823) Notes Isoperla bilineata is commonly referred to as the Two-lined Stripetail (Stark et al. 2012). This species is widespread across the eastern Nearctic, with records in Canada from Newfoundland west to Saskatchewan and southward in the USA to Mississippi, Alabama, and Florida, and west to Colorado (Szczytko and Kondratieff 2015, DeWalt et al. 2024). The sole record for this species representing the first report of this species in the state is based on a single ungravid female collected in late May 1926 (Fig. 38) from an approximate elevation of 125 m asl (Fig. 39) from Level IV Ecoregion Finger Lakes Uplands and Gorges (60 d) (Fig. 41 a). Additional material is needed to determine the status of this species in New York.
