Ostrocerca complexa ( Claassen, 1937)

Notes

Ostrocerca complexa is commonly referred to as the Notched Forestfly ( Stark et al. 2012). This species ranges from Quebec and the Canadian Maritime Provinces south along the Appalachian Mountains to Virginia and West Virginia ( DeWalt et al. 2024, Grubbs and Baumann 2023). In New York, adult collection dates range from mid-April to late June (Fig. 18 ). This species has been collected from elevations spanning 247-569 m asl (Fig. 19 ) from small spring-fed streams and seeps mainly in Level III Ecoregions Northeastern Highlands (58) and Northern Allegheny Plateau (60) (Fig. 20 a ).
