''G. veletis'' is a solitary, aggressive, omnivorous, burrow-inhabiting species of field cricket. This species is commonly confused with ''Gryllus pennsylvanicus'' (fall field cricket), as they inhabit the same geographical area. However, the two species are easily distinguished through examination of life history, ovipositor and behavioural differences. Predators of ''G. veletis'', and most field crickets, include American toads, wild turkeys, red-tailed hawks, wolf spiders and red-backed salamanders.〔Milne, L. Milne, M. 1980. ''National Audubon Society Field Guide to North American Insects and Spiders.''New York: Alfred A. Knopf〕 ==Identification== Adult body length measures approximately 22.0 mm (0.87 inches).〔 Males of this species are black with dark brown or black appendages.〔 Females are similar in colour and have a dark brown ovipositor, measuring approximately 14 mm (0.55 inches).〔 Female colouration differs from males as they have lighter, more reddish legs.〔 All species of field crickets generally look similar, with minor distinctions in morphological characteristics (i.e. coloration, ovipositor length, etc.) aiding in species identification. However, the male cricket's song play an important role in species identification. For an individual cricket, the species specific song helps distinguish mates and conspecifics from other species of crickets that might reside in the area.〔Walker, TJ. 1999, ''Field Crickets - Gryllus spp.'', http://entomology.ifas.ufl.edu/creatures/misc/crickets/gryllus.html#ref.
