What is the purpose of the pupa stage in insects?

The pupa stage in insects serves as a crucial transitional phase where the larva undergoes significant transformation—this is known as metamorphosis. During this stage, the insect does not feed; instead, it is primarily focused on reorganization and development. Inside the protective casing of the pupa, the insect’s body parts are restructured into their adult forms, including the formation of wings, legs, and reproductive organs, preparing the insect for its next life stage. This process is vital for the lifecycle of insects that undergo complete metamorphosis, ensuring their adaptation to environmental changes and maximizing their survival as adults.
