A male Gryllus cricket chirping: Its head faces its burrow; the leathery fore wings (tegmina; singular "tegmen") are raised (clear of the more delicate hind wings) and are being scraped against each other (stridulation) to produce the song. The burrow acts as a resonator, amplifying the sound.
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 chirping of the more common field crickets is not as reliably correlated to temperature—their chirping rate varies depending on other factors such as age and mating success. Dolbear expressed the relationship as the following formula which provides a way to estimate the temperature T F in degrees Fahrenheit from the number of chirps per ...
Gryllus bimaculatus is a species of cricket in the subfamily Gryllinae.Most commonly known as the two-spotted cricket, [2] it has also been called the "African" or "Mediterranean field cricket", although its recorded distribution also includes much of Asia, including China and Indochina through to Borneo.

Like most cricket species, Teleogryllus oceanicus males produce a calling song to attract potential female mates. Crickets produce the sound of their calls using a "file-scraper" system where, as the male opens and closes its wings, a plectrum (scraper) located on the posterior side of the left wing is rubbed against a filed vein located on the right wing.

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.
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.
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.
