Class Insecta


Members of the class Insecta have three body regions: the head, thorax, and abdomen. In their adult forms, insects typically have three pairs of legs, one pair of antennae and usually two pairs of wings. The head bears the mouth parts, eyes, brain, antennae and other sense organs, while the thorax usually bears the legs and wings. The abdomen, located behind the thorax, contains the digestive tract, reproductive organs and also houses the excretory system.
