What are the three main parts of an insect's body?

The three main parts of an insect's body are the head, thorax, and abdomen. This segmentation is a fundamental characteristic of the class Insecta. The head houses vital sensory organs and mouthparts for feeding; the thorax contains the legs and wings, facilitating movement and sometimes flight; and the abdomen contains important internal organs for digestion and reproduction. Understanding this basic anatomy is essential for recognizing how insects interact with their environments and can help in identifying specific characteristics important for pest control.
