Crickets, like other Orthoptera (grasshoppers and katydids), are capable of producing high-pitched sound by stridulation. Crickets differ from other Orthoptera in four aspects: Crickets possess three-segmented tarsi and long antennae; their tympanum is located at the base of the front tibia; and the females have long, slender ovipositors.

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.
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.

A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.” It tends to occur in ...
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.
At one time, nearly all the short-tailed crickets in the United States were considered to belong to the species Anurogryllus muticus, the range of which extended from Canada to much of South America. In a revision of the genus made by T. J. Walker in 1973, Anurogryllus arboreus was split off on the basis of the behavior of the male when calling ...
The burrow acts as a resonator, amplifying the sound. Most male crickets make a loud chirping sound by stridulation (scraping two specially textured body parts together). The stridulatory organ is located on the tegmen, or fore wing, which is leathery in texture. A large vein runs along the centre of each tegmen, with comb-like serrations on ...
Gryllotalpa gryllotalpa, commonly known as the European mole cricket, is widespread in Europe and has been introduced to the eastern United States. Its scientific name is derived from the Latin 'gryllus' ( cricket ); and 'talpa' ( mole ), because of the fine dense fur which covers it and its subterranean habits, [ 2 ] and because of the mole ...
