 Gryllus sp. (Field Cricket). | Field crickets are difficult to identify down to the species level. In the US, Gryllus has 16 species which are typically 15-30 mm long and darkly colored. Until the 1950s, native field crickets in eastern North America were all assigned to a single species, Acheta assimilis. Although regional variation in calling song and life history were noted, no morphological characters could be found to reliably distinguish these variants. bug guide (this photo): https://bugguide.net/node/view/1547032 wikipedia: https://en.wikipedia.org/wiki/Gryllus |
