Neoperla occipitalis (Pictet, 1841)

Notes

Neoperla occipitalis is commonly referred to as the Atlantic Stone ( Stark et al. 2012). Similar to N. coosa , this species is also patchily distributed in eastern North America. Records extend from Nova Scotia and in the USA from New York west to Wisconsin and Illinois and south to South Carolina, Alabama, and Mississippi ( Stark 2004, DeWalt et al. 2024). Based on our examination of material at CUIC, some historical records of N. clymene from New York State are applicable to this species. In New York, adults of this species were collected commonly at lights near larger rivers. Adult collection dates for this species range from late May to early August (Fig. 33 ) from rivers at elevations ranging from 50-535 m asl (Fig. 34 ) and broadly across the state (Fig. 36 e ).
