Grasshopper is a herbivorous insect of 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 because of its flapping wings while flying. Its rear femur is generally long and robust which is suitable for jumping.
These insects are generally winged, although their wings are sometimes unavailable to fly. The female locusts are generally larger than the male mantis.
