Grasshoppers are insects in the suborder Caelifera, probably the oldest living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. They are typically ground-dwelling insects with powerful hind legs which enable them to escape from threats by leaping vigorously. Defences against their many predators include camouflage, flight, and brilliantly coloured wing-flashes that can startle or distract an assailant. Some species have warning coloration. Grasshoppers share the order Orthoptera with crickets and their allies in the other suborder Ensifera. Some grasshopper species can change colour and behaviour to form locust swarms that can destroy crops and cause famine over wide areas. Even in smaller numbers, the insects can be serious pests. They are used as food in some countries, including Mexico and Indonesia. They feature in art, symbolism and literature.
