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 ).
