An individual locust might travel over 90 miles in a day, consuming its own weight in plant matter. A single swarm can cover up to 1200 square kilometers and can contain between 40 and 80 million locusts per square kilometer (a total of around 50 to 100 billion locusts per swarm, representing 100,000 to 200,000 tons, considering an average mass of 2 grams per locust). The locust can live between three and six months, and there is a ten to 16-fold increase in locust numbers from one generation to the next.
