Notes

This is an Appalachian-distributed species commonly known as the Truncate Needlefly ( Stark et al. 2012), and is known from Quebec and the island of Newfoundland south to North Carolina ( DeWalt et al. 2024). Harper and Hynes (1971 a) reported this species from small cold streams in southern Quebec, with adult emergence occurring late in the summer. Our collections from New York indicate a similar period of adult activity from mid-July through mid-September (Fig. 13 View Figure 13 ). In New York, Leuctra truncata has been reported from elevations ranging from 20-684 m asl (Fig. 14 View Figure 14 ) from Level IV Ecoregions Acid Sensitive Adirondacks (58 aa), Northern and Western Adirondack Foothills (58 ab), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad), Hudson Valley (59 i), and Catskills Transition (60 c) (Fig. 16 e View Figure 16 e ).
