Since a beetle is an insect, it has six legs. Each insect has a head, thorax, and abdomen on its body. The legs and wings of a beetle are joined to its abdomen.

The antennae of the beetle are found on its head, where they aid in locating food and a mate. These feelers can detect the vibrations that predators make. The reproductive and digestive systems of the insect are housed in the abdomen. Exoskeleton, also known as a hard shell that covers the entire body, serves as protective armour. Beetles exist in a variety of sizes, colours, and shapes, from ladybirds to lightning bugs to potato bugs, despite sharing the same fundamental structure.
