Notes

This species is commonly referred to as the Spiny Salmonfly ( Stark et al. 2012). Pteronarcys comstocki is an uncommon species distributed patchily from New Brunswick southeast to Kentucky and Tennessee ( DeWalt et al. 2024, Nelson 2000). In New York, this species is known from scattered localities in Level IV Ecoregions Adirondack High Peaks (58 z), Acid Sensitive Adirondacks (58 aa), Eastern Adirondack Foothills (58 ac), Finger Lakes Uplands and Gorges (60 d), and Mohawk Valley (83 f) (Fig. 44 e View Figure 44 e ). Adults have been collected in the state from late May to early June (Fig. 45 View Figure 45 ) and appear to prefer cold pristine rivers and larger streams at elevations ranging from 164-442 m asl (Fig. 46 View Figure 46 ).
