Locust Plague Devours 40,000 Tonnes of Vegetation | Earth’s Tropical Islands | BBC Earth BBC Earth 11.8M subscribers Subscribe


Locusts. They’re normally solitary insects, but when there’s an abundance of crops, then numbers can reach plague proportions. These flightless hoppers can form armies a kilometre long, but they have only. Just begun on their path of destruction. Five weeks old, they move. It’s a fully fledged adults and can take to the air. A swarm this size may only happen once in a decade, not just travelling over 18 kilometres a day. They can develop 40,000 tonnes of vegetation, including farmers, precious rice crops. On reaching the highlands, a plague is finally stopped by the heavy mountain rains. Wet wings prevent the locusts from flying until eventually the swarm runs. Out of food. And dies.
