Alloperla atlantica Baumann 1974

Alloperla atlantica Baumann, 1974 Notes Alloperla atlantica is commonly referred to as the Atlantic Sallfly (Stark et al. 2012). The distribution of this species extends from the Canadian Maritime Provinces and Quebec west through the northern Laurentian Great Lakes region to Minnesota and southwest to Tennessee and Alabama (Surdick 2004, DeWalt et al. 2024). Harper and Pilon (1970) reported a short synchronous emergence from late May to mid-June in Quebec. This species was commonly collected in the eastern half of the state (Fig. 25 d). Further surveys in western New York should yield additional records. Adults in New York had an extended flight period with adults present from late May through early August (Fig. 26) at elevations from 49-620 m asl (Fig. 27).
