Locusts are known to have devastated plants and crops throughout the ages.

They migrate thousands of miles in search of food.

A typical swarm can contain 500,000 million insects,

measuring 30 miles in length and 5 miles in width.

They appear as a vast black cloud hiding the sun!

They can eat each day the amount of food needed by 20 million people.

The migrations seem to be triggered by the sudden population explosion

in the desert areas where they breed.
