Crickets are fascinating orthopteran insects with distinctive sounds. They are closely related to bush crickets and grasshoppers. Crickets have cylindrical bodies, round heads, and long antennae. The front wings are hardened and function as protective covers, while the hind wings are membranous. Many crickets produce their characteristic chirping sound by rubbing body parts together. They are mainly nocturnal and known for the loud, persistent songs sung by males to attract females. Crickets are found worldwide, except at latitudes 55° or higher, and inhabit diverse habitats ranging from grasslands to caves. They have cultural significance in literature, folklore, and even as pets and a potential food source.
