Scientists call insects the most successful animals on Earth. Of all the millions of animals on our planet, eight out of every ten are some kind of insect. Insects are arthropods that have six jointed legs. Insects live in deserts, forests, grasslands, mountains, and cities. Some even live in aquatic environments, like freshwater ponds, lakes, and streams. Some live underground, others fly through the treetops. Most are less than 1 cm long. But a few, such as tropical stick insects, are giants. Some of the most well known insects are butterflies, beetles, dragonflies, cockroaches, and social insects like ants, termites, and bees.
