A cricket has six legs and belongs to the scientific order 'Orthoptera.' Two pairs of legs are attached to the thorax, while the hind legs are attached to the abdomen.
The forelegs and middle legs, or "walking legs," are almost identical. The hind legs, however, are much larger and make it possible for the cricket to hop or escape easily from predators. While it is a popular myth that a cricket chirps by rubbing its legs together, the chirp actually comes from the stridulatory organ, a large vein that runs along the bottom of each wing, and is done only by males.
