Insects are small animals that live in environments full of movement, like climbing on grass and flying through the air. They matter because they are an abundant and active part of the natural world, interacting constantly with their surroundings and other living things.

Insects (from Latin ') are hexapod invertebrates of the class Insecta'''. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species.
