In an incomplete metamorph insect, which stage is not part of the life cycle?

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

Answer: (C)

In incomplete metamorphosis, growth happens through molts of immature nymphs that resemble the adult, with no pupal stage. The life cycle goes from egg to nymph to adult, and the nymphs progressively develop into the adult form through several molts. A pupal stage is characteristic of complete metamorphosis, where a larva is transformed inside a chrysalis or puparium. So, in incomplete metamorphosis, the stage that does not occur is the pupal stage. The egg, nymph, and adult stages are all part of the cycle.
