Only a male cricket chirps using its ridges, or teeth that act like a comb and file instrument. The left forewing of male cricket is a modified vein or a thick rib containing about 50 to 300 minute teeth, which they raise up to a 45-degree angle and rub against upper hind edge of their right forewing, which has a type of built-in scraper. This act of chirping is scientifically known as stridulation and is specific to the cricket species. There are two main types of songs that a cricket sings, namely the courting song and the calling song. The calling song is a fairly loud, shrill, high-pitched number which attracts the female cricket towards the male and repels other male crickets, who are often rival suitors. The courting song is more like a quiet ballad sung by the male when the female is nearby, and is relatively softer than the calling song.
