Leuctra variabilis

is one of the few stoneflies reported from unusual habitats for stoneflies, bogs with imperceptible flow and pitcher plants (Nelson et al. 2002). Leuctra variabilis emerges rather late compared to most other Leuctra species, from late September to early December. Only 2 previous Pennsylvania records exist, from Susquehanna and Wyoming Counties in northeastern Pennsylvania (Masteller 1996). Leuctra variabilis has been reported from New England south to Maryland.

New record: CARBON: (D) unnamed tributary to Lizard Creek, 20 m upstream of T-334, 16 October 2003, 1♂ (TD).
