Insect. By rubbing legs and wings against their body, locusts make a humming sound. They can hear this hum and a range of other sounds through ears on their abdomens. Adults grow to 7 cm (3 in) long, eating the equivalent of their own weight in a day. Locusts are larger than grasshoppers and have transparent wings. They can fly for 15 hours at a time. When a lot of locusts come together, they change color and form a swarm that can be miles wide, blotting out the sun and devouring every plant in its path. The largest known swarm covered 1,036 sq km (400 sq mi) and was made up of 40 billion insects.
