Cricket flour is used in protein bars, pet foods, livestock feed, nutraceuticals, and other industrial applications. The United Nations says that the use of insect protein, such as cricket flour, could be critical in feeding the growing population of the planet while being less damaging to the environment. [58]
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 house cricket is typically gray or brownish in color, growing to 16–21 millimetres (0.63–0.83 in) in length. Males and females look similar, but females will have a brown-black, needle-like ovipositor extending from the center rear, approximately the same length as the cerci, the paired appendages towards the rear-most segment of the cricket.
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.

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.

Gryllus is a genus of field cricket (Orthoptera, Gryllidae, Gryllinae). Members of the genus are typically 15–31 mm long and darkly coloured. [ 2 ] The type species is Gryllus campestris L.: the European field cricket.
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 ...
