Notes

This species is commonly referred to as the Plateau Sallfly ( Stark et al. 2012), and is known from unglaciated portions of the Alleghany and Cumberland Plateaus from New York southwest to Alabama and west across Ohio ( DeWalt et al. 2016) to Indiana ( DeWalt and Grubbs 2011, Kondratieff and Kirchner 2009, DeWalt et al. 2024). Fishbeck (1987) reported an early June to mid-July emergence of this species (as S. onkos ) from Gray’s Run in northeastern Ohio. In New York, adults of this species have been recorded from early May through early June (Fig. 26 View Figure 26 ) at elevations ranging 300-422 m asl (Fig. 27 View Figure 27 ) from small streams in Level IV Ecoregions Glaciated Low Allegheny Plateau (60 a), Low Lime Drift Plain (61 c), and Finger Lakes Uplands and Gorges (60 d) (Fig. 29 f View Figure 29 f ).
