The most numerous animals on Earth are insects. They form about 75 percent of the animal kingdom.

Around 800,000 species have been identified, but there may be up to 10 million.

Some insects live in colonies.

Many insects can fly, which makes it easy for them to colonize new places.

Insects eat a huge range of foods. Around half are plant-eaters, feeding on leaves, roots, seeds, nectar, or wood. Fleas and lice are parasites, eating the flesh or blood of larger animals without killing them.

WHAT DO INSECTS EAT?

WHERE DO INSECTS GO IN WINTER?

Some adult insects die off in winter. Their eggs or young survive in sheltered places and emerge in spring.

Others, such as monarch butterflies, migrate long distances to avoid the winter chill .

HOW DO INSECTS AFFECT HUMANS?

Plant-eating insects can harm crops and fruit trees. Wood-munching insects destroy homes and furniture, while biting insects can spread disease. However, many insects are helpful to humans—for example, honeybees make honey and silkworms produce silk.

An Australian tiger beetle is the world’s fastest running insect. It can reach speeds of 9 kilometers per hour .

FACINATING FACTS ABOUT ANIMALS

Insects have many different ways of communicating. They communicate through touch with their antennae and mouths.

Insects don’t need much water, however: a simple raindrop will do.

The fastest flying insect is Horse Fly. Its fastest recorded speed is 145 km per hour.
