Solitary grasshoppers are passive, minding their own business. Bunch them together in close quarters and it is a different story. Close together their hind legs kick their neighbours many times per minute; then watch out!! Serotonin courses through their little grasshopper brains and they then have an “Incredible Hulk” metamorphosis. Apart from becoming super horny, they double in size, become brightly coloured, super aggressive, and fly long distances, eating their weight in a day. Eating themselves out of house and home (like teenage humans) they swarm to new areas to eat, rendering the landscape devoid of vegetation.
