Leuctra duplicata Claassen 1923

Leuctra duplicata Claassen, 1923 Notes Leuctra duplicata is commonly known as the Atlantic Needlefly (Stark et al. 2012), and is distributed from southeastern Canada south to North Carolina (Grubbs and Wei 2017, DeWalt et al. 2024). Harper (1990 a) found that larvae of L. duplicata displayed a fast, univoltine life cycle in an intermittent stream in southern Quebec. Turner et al. (1996) reported larvae and adults of L. duplicata and L. maria from pitcher plants (Sarracenia purpurea L.), although it is likely that these individuals entered the plants during emergence from the surrounding bog habitat (Stewart and Stark 2002). All across New York, adults have been collected from mid-May to mid-June (Fig. 13) and commonly from spring seeps and smaller streams at 135-1262 m asl (Fig. 14) across the state (Fig. 15 c).
