Range: In most of its range, Gryllus firmus is the only chirping, field-inhabiting Gryllus. In South Florida it overlaps with Gryllus assimilis. To the north its range overlaps with G. veletis and G. pennsylvanicus and it sometimes hybridizes with the latter species (Harrison and Bogdanowicz 1997).
