Which term describes the life cycle stage of insects that undergoes metamorphosis?

The term that describes the life cycle stage of insects undergoing metamorphosis is 'Pupa.' This stage is a crucial part of complete metamorphosis, which consists of four stages: egg, larva, pupa, and imago (adult). During the pupal stage, the insect undergoes significant transformation, often inside a protective casing. The pupa serves as the transitional phase between the larval and adult stages, during which the organism is reorganizing and developing the structures and functions necessary for its adult form. This transformation process is vital for the development of adult characteristics, enabling the insect to emerge as an imago fully formed and capable of reproduction. Understanding the role of the pupa in the metamorphic cycle highlights the complexities of insect development and the remarkable changes these organisms undergo throughout their life cycle.
