The desert locust is one of about a dozen species of grasshoppers known as locusts which - unlike other grasshoppers - are able to change their behaviour in response to population density. This enables them to form swarms that can migrate over large distances. Locust swarms vary from less than one square kilometre to several hundred square kilometres. There can be from 40 million to as many as 80 million locust adults in each square kilometre of a swarm.
Scientific name: Schistocerca gregaria
A plague of biblical proportions occurs as billions of voracious insects fill the air.
'An average sub-Saharan swarm of desert locusts may number 50 billion and they will consume four times as much food as the humans living in New York or London in a single day. Insect spectacles don't come much bigger than this and I'd love to see it first hand.' (George McGavin on his list of top wildlife spectacles still to see)
