Gryllus fultoni
Southern Wood Cricket
Gryllus fultoni, the southern wood cricket, is a field cricket species found in the southeastern United States. It overwinters as a juvenile and matures in spring, inhabiting forested environments. The species produces a distinctive calling song consisting of fast-pulsed chirps. In areas of sympatry with Gryllus vernalis, G. fultoni exhibits reproductive character displacement, with divergence in calling song characters and mirror area that enhances reproductive isolation.
