Alloperla idei (Ricker, 1935)

Notes

This species is commonly referred to as the Vernal Sallfly ( Stark et al. 2012). Alloperla idei has been reported from New Brunswick west to Ontario and patchily southwest to Alabama and Georgia ( Surdick 2004, DeWalt et al. 2024). DeWalt et al. (2016) reported adults from three small streams in May in the southeastern Ohio portion of the Appalachian Plateau. Harper and Pilon (1970) documented peak emergence of this species in late May and early June from a Quebec stream. In New York, adults were collected from mid-June to mid-July (Fig. 26 ) at elevations ranging from 43-563 m asl (Fig. 27 ). This species can be common in Level IV Ecoregions Acid Sensitive Adirondacks (58 aa), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad). Hudson Valley (59 i), Catskills Transition (60 c), and Ontario Lowlands (83 c) (Fig. 28 b ).
