Alloperla chloris Frison 1934

Alloperla chloris Frison, 1934 Notes Alloperla chloris is commonly referred to as the Triangular Sallfly (Stark et al. 2012). This species has an Appalachian distribution from southeastern Canada south to Alabama and Georgia (Surdick 2004, DeWalt et al. 2024). Fishbeck (1987) and DeWalt et al. (2016) reported this species from small streams in the glaciated northeastern corner of Ohio where adults were taken from May to August. Most records of this species are from eastern areas of New York (Fig. 25 f), but it is likely more abundant and widespread than current collections indicate. In New York, adults have been collected between early June and mid-August (Fig. 26) from upland streams and rivers at elevations ranging from 97-568 m asl (Fig. 27).
