Song of a Fast-tinkling Trig (scroll down for explanation and additional recordings!).

Anaxipha tinnulacitaT he Fast-tinkling Trig is a strikingly handsome member of the small-cricket tribe known as trigs. They are found in weedy fields, brushy understories, hedgrows, and riparian habitats. They are associated with Say’s and Slow-tinkling Trigs. Fast-tinkling Trigs are always on the move, rarely sitting still for more than a couple of seconds. They are more easily seen at night when they are up in the vegetation, about a meter or so off the ground.

Fast-tinkling Trigs were found by this author in Jefferson and Berkeley Counties of West Virginia in August of 2019. This was the first documented record for this species in West Virginia.
