Locusts follow the food source. Once they have devastated the vegetation in one area, they migrate to another area to feed.
Normally the numbers of locusts are not too intrusive. But when the locusts swarm in vast numbers and migrate to new areas, human food crops can be stripped bare.
Desert locusts migrate under a variety of conditions. These include a lack of food, changing weather conditions and the presence of predators.
Locusts differ from grasshoppers in that they have the ability to change their behaviour and habits and can migrate over large distances but they do so when their population reaches a peak in numbers. Other wise they could live a lonely life.
They have to keep migrating because they consume all the available food sources in a given area, and then must move on to find more.
There are not many places where locusts do not live. They have become extinct in the Rocky Mountains due to mining. However, they migrate and can destroy crops.
