Most female crickets lack the necessary adaptations to stridulate, so make no sound. [7] Several types of cricket songs are in the repertoire of some species. The calling song attracts females and repels other males, and is fairly loud. The courting song is used when a female cricket is near and encourages her to mate with the caller.
The female is attracted to the song of the male cricket and deposits larvae on or around him, as was discovered in 1975 by the zoologist William H. Cade. [3] Ormia ochracea is a model organism in sound localization experiments because of its unique "ears", which are complex structures inside the fly's prothorax near the bases of its front legs ...
Unlike females, however, males are able to produce sounds or chirps. Thus, males can be identified through sound while females cannot. Diagram A shows the male cricket with its wings raised for the purpose of chirping. Diagram B shows the female cricket, identified via the long protruding ovipositor at the end of the abdomen.
The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
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.

This range of frequencies is called a carrier frequency. Tree crickets are unique in the way they use carrier frequencies because the range of frequencies changes according to the temperature. Due to this, female tree crickets have tympanum (hearing organs) that can receive a much wider range of frequencies than most other insects. [6]
However, in other cases, the female receives few, if any, benefits. [30] The reproductive behavior of bush crickets has been studied in great depth. Studies found that the tuberous bush cricket (Platycleis affinis) has the largest testes in proportion to body mass of any animal recorded. They account for 14% of the insect's body mass and are ...
