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 ...
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. [1]
All these insects have four tarsal segments and are probably more closely related to each other than they are to the true crickets, Gryllidae. [2] The body is cylindrical in most Grylloideans, but in some it is oval. The antennae are long and threadlike, except in the family Gryllotalpidae in which they are much shorter and brush-like.
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.
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 tropical house cricket is slightly smaller than its relative the house cricket, growing about 13–18 mm (0.51–0.71 in). These crickets are light yellowish tan and have two thick black bands.
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.
