Notes

Sweltsa lateralis is commonly known as the Curved Sallfly ( Stark et al. 2012). This common and widespread species is distributed in Canada from New Brunswick west to Ontario and in the USA mainly along the Appalachian Mountains from Maine south to Tennessee ( Surdick 2004, DeWalt et al. 2024). Previous life history studies of this species have indicated a multivoltine-slow two-year life cycle ( Huryn and Wallace 1987.) Fishbeck (1987) reported the adult flight period for S. lateralis from early June to mid-July in northeastern Ohio. Adults are present in New York from early May through mid-August (Fig. 26 View Figure 26 ) at elevations ranging from 98-1623 m asl (Fig. 27 View Figure 27 ). This species was widely distributed in small streams and rheocrenes, with distributional records available from upland areas across the state (Fig. 30 a View Figure 30 a ).
