They protect themselves from predators by camouflage; when detected, many species attempt to startle the predator with a brilliantly-coloured wing-flash while jumping and (if adult) launching themselves into the air, usually flying for only a short distance. Other species such as the rainbow grasshopper have warning coloration which deters predators. Grasshoppers are affected by parasites and various diseases, and many predatory creatures feed on both nymphs and adults. The eggs are the subject of attack by parasitoids and predators. br br Grasshoppers have had a long relationship with humans. Swarms of locusts have had dramatic effects that have changed the course of history, and even in smaller numbers grasshoppers can be serious pests. They are eaten as food and also feature in art, symbolism and literature.
