Isoperla slossonae ( Banks, 1911)

Notes

This species is currently known as the Colorful Stripetail ( Stark et al. 2012) and has been recorded in Canada from Quebec and the Canadian Maritime Provinces south in the USA to North Carolina and from Michigan west to Minnesota and Iowa ( Szczytko and Kondratieff 2015, DeWalt et al. 2024). Hilsenhoff and Billmyer (1973) reported a univoltine life cycle for this species in small to medium-sized streams in Wisconsin. We report adult collection dates in New York for I. slossonae from mid-April to late June (Fig. 38 ). Although this species was not reported from New York by Szczytko and Kondratieff (2015), we have confirmed records at low elevations ranging from 3-169 m asl (Fig. 39 ) from streams and rivers in Level IV Ecoregions Taconic Foothills (58 x), Adirondack High Peaks (58 z), Eastern Adirondack Foothills (58 ac), Central Adirondacks (58 ad), and Cape Cod / Long Island (84 a) (Fig. 43 f ).
