Grasshopper is a herbivorous insect of the suborder of Caelifera in 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.
