Remenus bilobatus

Remenus bilobatus (Needham & Claassen, 1925) Notes This species is commonly known as the Lash Springfly (Stark et al. 2012) with distributional reports from Connecticut and New York south along the Appalachian Mountains to Alabama and Georgia (Kondratieff 2004, Verdone and Kondratieff 2018, DeWalt et al. 2024). The life history and ecology of R. bilobatus are unknown. Although originally described from New York, few collections of this species have been made since its initial description from Old Forge in Herkimer County. Records of this species in the state indicate a late summer emergence, with adults collected from late June through early August (Fig. 38). We have collected both nymphs and adults of R. bilobatus at elevations ranging from 106-637 m asl (Fig. 39) from small spring-fed streams in Level IV Ecoregions Eastern Adirondack Foothills (58 ac) and Central Adirondacks (58 ad) (Fig. 44 c).
