In complete metamorphosis, which life stage is typically immobile and encased in a protective covering?

• A. Pupa
• B. Egg
• C. Larva
• D. Adult

Answer: (A)

In complete metamorphosis, the pupal stage is the period of transformation where the insect is largely inactive and protected inside a covering, such as a chrysalis or cocoon. During this time, the organism isn’t feeding or moving much as it reorganizes its tissues and organs from larval form into the adult form. The covering provides crucial protection while these dramatic changes occur, and only after this transformation emerges the mobile, functional adult. The egg is just the starting stage and isn’t the phase where growth into a drastically different body plan happens. The larva is typically active and feeding, not immobile, and the adult is mobile and reproductive but not undergoing the metamorphic change.
