Leuctra tenella Provancher 1878

Leuctra tenella Provancher, 1878 Notes Leuctra tenella is commonly known as the Broad-Lobed Needlefly (Stark et al. 2012) and is known from mainland Labrador west to Minnesota and southwest along the Appalachian Mountains to Georgia (Grubbs 2015, DeWalt et al. 2024). Harper and Hynes (1971 a) reported this species from small spring-fed streams. In New York, adults of L. tenella have been reported from mid-May to early September (Fig. 13) from a wide range of elevations (135-1551 m asl; Fig. 14). This species was frequently collected from Level III Ecoregions Northeastern Highlands (58) and the Eastern Great Lakes Lowlands (83) and is likely more common than collections indicate in western New York (Fig. 16 b).
