Isoperla orata Frison 1942

Isoperla orata Frison, 1942 Notes Isoperla orata is commonly known as the Colorless Stripetail (Stark et al. 2012). This species is known from Canada from Nova Scotia west to Quebec and in the USA from Maine southwest mainly along the Appalachian Mountains to Tennessee and South Carolina, with a disjunct distribution present in Minnesota (Szczytko and Kondratieff 2015, DeWalt et al. 2024). Harper and Pilon (1970) reported the emergence of this species in early June in Quebec. In New York, adults have been collected between mid-May through early August (Fig. 38) from a wide range of elevations (175-821 m asl; Fig. 39). Although this species is known mainly from Level III Ecoregions Northeastern Highlands (58), Northern Allegheny Plateau (60), and Eastern Great Lakes Lowlands (83) (Fig. 43 b), further collections in western New York would likely yield additional records.
