How they produce the sound?
Only male crickets actually produce sounds.The male crickets chirps to attract a female mate. The female responds only to the unique, characteristic sound of her own species. Crickets also chirp to establish their territories and defend it against competing males.
Crickets produce by rubbing their wings together. At the base of the forewing, a thick, ridged vein acts as a file. The upper surface of the forewing is hardened, like a scraper. When the male cricket wants to call for a mate, he lift his wings and pulls the file of one wing across the scraper of the other. The thin, papery portions of the wings vibrate, amplifying the sound.
