Most of the world's insect species-including butterflies, moths, true flies, ants, bees, and beetles-are holometabolous. After the reorganization is complete, the pupa molts to reveal a mature adult with functional wings. The larval tissues and organs break down entirely, then reorganize into the adult form.

The pupal stage is usually considered a resting phase, although many active changes are occurring internally, hidden from view. dragonfly, (suborder Anisoptera), also called darner, devil’s arrow, or devil’s darning needle, any of a group of roughly 3,000 species of aerial predatory insects most commonly found near freshwater habitats throughout most of the world. When the larva molts for the final time, it transforms into a pupa. Some insect orders have unique names for their larval forms: butterfly and moth larvae are caterpillars fly larvae are maggots, and beetle larvae are grubs. Larvae grow and molt, usually multiple times. Their habitats and food sources may be entirely different from the adults as well. Entomologists call insects that undergo complete metamorphosis "holometabolous," from "holo," meaning "total." The larvae of holometabolous insects bear no resemblance to their adult counterparts. Each stage of the life cycle-egg, larva, pupa, and adult-is marked by a distinctly different appearance. Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. There is no pupal stage in the life of a dragonfly. Most insects undergo complete metamorphosis over the course of a lifetime. Unlike butterflies or mosquitoes, which undergo a complete, four-stage metamorphosis, dragonflies undergo three stages of development known as incomplete metamorphosis.
