(Blatchley, 1900)

Sphagnum Ground Cricket, Marsh Ground Cricket

Neonemobius palustris is a small in the Trigonidiidae, found in eastern North America. Males measure approximately 5.7 mm and females about 6.8 mm in length. The is strongly associated with moist , particularly dense of sphagnum moss, sandhill seeps, and wet longleaf pine savannas. It produces a distinctive calling song consisting of trills several seconds in duration separated by pauses of similar length.
