Insects are arthropods because they share jointed appendages, segmented bodies, and a chitin-based exoskeleton. These features distinguish them from chordates, echinoderms, and molluscs.

The insect cuticle includes an outer epicuticle and deeper procuticle regions such as exocuticle and endocuticle. This layered design provides protection, support, and resistance to water loss.

Adult insects typically show tagmatosis into head, thorax, and abdomen. The head handles feeding and sensory functions, the thorax bears legs and wings, and the abdomen contains many visceral and reproductive organs.

Tagmatosis means body segments are grouped into specialized regions called tagmata. In insects, this produces the head, thorax, and abdomen, allowing different body regions to perform feeding, locomotion, and reproduction efficiently.
