Bolotoperla rossi ( Frison, 1942)

Notes

Bolotoperla rossi is commonly referred to as the Smoky Willowfly ( Stark et al. 2012). This is an Appalachian-distributed species reported from Quebec and Maine south to South Carolina and Tennessee ( Stewart 2000, Stark et al. 2016, DeWalt et al. 2024.) Prior reports of this species from New York by Stewart (2000) are based on a misinterpretation of the holotype locality “ Near Woodstock, Bog Brook, NH ”. Myers et al. (2011) reported this species from the Adirondack Park but without locality data. Larvae of this species were previously documented from 2 nd- to 4 th-order Appalachian streams with peak emergence occurring in March and early April ( Kirchner and Harper 1983). In New York, this species appears to be common and has been reported from larger streams and rivers in Level IV Ecoregions Adirondack High Peaks (58 z), Acid Sensitive Adirondacks (58 aa), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad), and Champlain Lowlands (83 b) (Fig. 21 e ). Adult collection dates ranged from early April to the end of June (Fig. 22 ), at elevations ranging from 144-639 m asl (Fig. 23 ).
