Crickets, family Gryllidae (also known as 'true crickets'), are insects somewhat related to grasshoppers, and more closely related to katydids or bush crickets (family Tettigoniidae) and Weta (families Anostostomatidae and Rhaphidophoridae). They have somewhat flattened bodies and long antennae. There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure including jumping hind legs. Crickets are harmless to humans.
