Many insects live in groups, swarms, colonies or nests. A colony of ants can have just 50 ants. One big nest in Japan had 1,080,000 queen ants and 306,000,000 workers in 45,000 smaller nests, each of which was connected with the others. Some insects, like locusts, live in swarms. One swarm can hold 28,000,000,000 locusts. When A locust swarm attacks a field, it’s bad news for the farmer. Each locust weighs only about 2.5 grams (0.09 ounce). But an average swarm has a weight of 70,000 tons!
