Until the mid-1950s, native field crickets in eastern North America were all assigned to a single species, Acheta assimilis Fabricius. Although regional variation in calling song and life history were noted,[3][4] no morphological characters could be found to reliably distinguish these variants.[5] Building upon the pioneering work of Fulton,[4] Alexander [5] used male calling song, life history and crosses between putative species to revise the taxonomy of gryllines in the eastern United States, and recognized five species, although at the time they were still classified in the genus Acheta.


The genus contains the following species :[6][7]
