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).
