Alloperla vostoki Ricker, 1947

Notes

This species is commonly referred to as the Scotia Sallfly ( Stark et al. 2012). Similar to A. voinae , this rare species is also considered vulnerable to extirpation or extinction ( NatureServe 2024). Alloperla vostoki has been reported infrequently in Canada from Nova Scotia and New Brunswick and in the USA from Maine, New York, and Pennsylvania ( Surdick 2004, DeWalt et al. 2024). This species was collected most efficiently with beating sheets and UV light trapping methods. Adults of this species have been collected in New York from early June through early July (Fig. 26 ) at elevations ranging from 88-466 m asl (Fig. 27 ) from sporadic locations in Level IV Ecoregions Catskill High Peaks (58 y), Tug Hill Transition (58 af), Hudson Valley (59 i), Glaciated Low Allegheny Plateau (60 a), Finger Lakes Uplands and Gorges (60 d), Ontario Lowlands (83 c), and Mohawk Valley (83 f) (Fig. 29 a ). This species was encountered in small to medium sized streams and rivers with underlying shale formations.
