Swarms of locusts are currently on the rampage in Maharashtra, Uttar Pradesh and Punjab, after leaving a trail of destroyed crops in Rajasthan, Gujarat, Madhya Pradesh and Haryana. These are no ordinary hoppers in that they become dangerous when they enter the gregarious phase, by forming swarms that can travel up to 150 km per day and eat as much as about 10 elephants in a day. When millions of locusts descend on a crop, they destroy everything, devastating the agricultural supply chain and livelihoods of farmers.
