endopterygota

Endopterygota is a group of insects that undergo complete metamorphosis, meaning their development includes distinct stages: egg, larva, pupa, and adult. During these stages, their appearance and form change significantly. Examples include butterflies, beetles, and flies. The key feature of Endopterygota is that the transformation from immature to adult happens inside a protective casing called a pupa, allowing for a complete overhaul of their body structure. This process helps them adapt to different environments and ecological roles throughout their lifecycle.
