Locusts are herbivorous insects from the suborder of Caelifera in the Orthoptera order. This insect has an antenna that is almost always shorter than its body and also has a short ovipositor. the sound generated by some grasshopper species is usually produced by rubbing the rear femur against the front or abdominal wings (called stridulation), or by flapping its wings while flying. The rear femur is generally long and strong which is suitable for jumping.

These insects are generally winged, although their wings sometimes can not be used to fly. The female locusts are generally larger than the male grasshoppers.
