Bush crickets, which number over 6,000 species, can be found on every continent except Antarctica. They are usually spotted amongst vegetation, where they can mimic leaves and sticks or just hide away. The males rub modified front wings to produce the loud sound (called stridulation) that begins the mating process. Females are usually silent. On rare occasions swarms of bush crickets can cause serious damage to crops.
Scientific name: Tettigoniidae
Insects in the family Tettigoniidae are commonly called katydids or bush-crickets. There are more than 6,400 species. Part of the suborder Ensifera, it is the only family in the superfamily Tettigonioidea. The name is derived from the genus Tettigonia, first described by Carl Linnaeus in 1748. They are also known as long-horned grasshoppers, although they are more closely related to crickets and weta than to any type of grasshopper. Many tettigoniids exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves.
