What stage of complete metamorphosis is characterized by a non-feeding phase where the insect transforms into an adult?

The correct answer is the pupal stage. During this stage, the insect is typically encased in a protective structure where significant internal and external changes occur as it transitions from larva to adult. This non-feeding phase is crucial for the transformation because the insect’s body is reorganizing—developing wings, reproductive organs, and other adult features.

Insects at this stage generally do not consume food, focusing entirely on metamorphosis. The remarkable changes occurring in the pupal stage lay the groundwork for the adult stage, in which the fully formed insect will emerge, ready to take on the responsibilities of reproduction and survival.

Understanding this stage is vital in the study of entomology and the life cycles of insects, as it highlights the complex processes involved in transformation.
