Notes

Isoperla lata is currently known as the Dark Stripetail ( Stark et al. 2012). This species has been reported from Canada from mainland Labrador and Nova Scotia west to Ontario and in the USA from Maine in parallel fashion west to Minnesota plus southwest along the Appalachian Mountains to North Carolina and Tennessee ( Szczytko and Kondratieff 2015, DeWalt et al. 2024). Sandberg and Szczytko (1997) suggested a univoltine-slow larval life cycle for I. lata in central Wisconsin. In Quebec, adults have been reported from early May to late June ( Harper and Magnin 1969). The limited adult flight period data in New York of only early March (Fig. 38 View Figure 38 ) is based on reared material. We report collections of this species from elevations ranging from 170-218 m asl (Fig. 39 View Figure 39 ) from the Boquet River in Level IV Ecoregions Eastern Adirondack Foothills (58 ac) and Champlain Lowlands (83 b) (Fig. 42 c View Figure 42 c ). This species is likely more common in the state than collections indicate and is easily distinguished as larvae from other members of this genus by the distinct lacinia setation.
