Insects are arthropods which have an exoskeleton that is chitinous and a body divided into three parts (head, thorax, and abdomen). Other important features of their body are the antennae, compound eyes, and legs. The total number of insect species documented are more than 1 million. Such is the diversity and variety among the species that half of the living ones belong to the class Insecta.
