Pteronarcys dorsata

Pteronarcys dorsata (Say, 1823) Notes Pteronarcys dorsata is commonly known as the American Salmonfly (Stark et al. 2012). The range of this transcontinental species extends from Labrador and New Brunswick west across Canada to Alaska and south to Wyoming and from south from Maine to the USA Gulf Coastal region from Florida west to Louisiana (Nelson 2000, DeWalt et al. 2024). Barton (1980) suggested a three-to-four-year life cycle for this species in Alberta. In contrast, Lechleitner and Kondratieff (1983) suggested a univoltine life cycle for this species in Virginia. In New York, this species has been collected from across the state and is largely associated with large streams and rivers (Fig. 44 f). Adults have been collected sporadically in the state from mid-March through mid-June (Fig. 45) at elevations ranging from 41-418 m asl (Fig. 46).
