Gryllinae, or field crickets, are a subfamily of insects in the order Orthoptera and the family Gryllidae. They hatch in spring, and the young crickets (called nymphs) eat and grow rapidly. They shed their skin eight or more times before they become adults. Field crickets eat a broad range of food: seeds, plants, or insects (dead or alive).
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets.Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (e.g. Imms [3]): taxa such as the tree crickets, spider-crickets and their allies, sword-tail crickets, wood or ground crickets and scaly crickets have been ...
Gryllacrididae are a family of non-jumping insects in the suborder Ensifera occurring worldwide, known commonly as leaf-rolling crickets or raspy crickets.The family historically has been broadly defined to include what are presently several other families, such as Stenopelmatidae ("Jerusalem crickets") and Rhaphidophoridae ("camel crickets"), [1] now considered separate.
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms , [ 3 ] "crickets" were placed at the family level ( i.e. Gryllidae ), but contemporary authorities including Otte now place them in the superfamily Grylloidea .

Spring field crickets are often grouped with the other species of field crickets when discussing their possible impacts on humans. Field crickets, including G. veletis, are generally omnivorous scavengers. Their diet normally consists of plants, both fresh and decaying, other dead insects and in some cases predation of other field crickets or ...
Mole crickets are the only insects that construct a sound-producing apparatus. Given the known sensitivity of a cricket's hearing (60 decibels), a night-flying G. vineae female should be able to detect the male's song at a range of 30 m; this compares to about 5 m for a typical Gryllus cricket that does not construct a burrow.

Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, thin tibiae, and long, slender antennae. The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs.
At one time, many field crickets found in the eastern states of the United States were assumed to be a single species and were referred to as Gryllus assimilis.However, in 1932, the entomologist B. B. Fulton showed that four populations of field cricket in North Carolina, that were morphologically identical and which were all considered to be G. assimilis, produced four different songs.
