Why are centipedes in the insect catergory?

Centipedes are not classified as insects; they belong to the class Chilopoda, which is distinct from the class Insecta. While both groups are arthropods, centipedes have a different body structure, including a more elongated body with numerous segments and one pair of legs per body segment, unlike insects which have three main body parts and six legs. This classification highlights the diversity within arthropods, where centipedes are more closely related to other myriapods than to insects.
