In gradual metamorphosis, what is true about the adult stage?

• A. Adults are winged and sexually mature with no further growth
• B. Adults remain larval-like
• C. Adults pupate
• D. Adults never reach maturity

Answer: (A)

Gradual metamorphosis (incomplete metamorphosis) involves eggs, nymphs, and adults, with nymphs that resemble smaller versions of the adult and molt until they reach the adult form. There is no pupal stage, and growth ends with the final molt. The adult is sexually mature and, if the species has wings, those wings are fully developed. There is no further growth after becoming an adult. That’s why the statement that adults are winged and sexually mature with no further growth is the best fit. (Note: some species may have wingless adults, but the common pattern described here emphasizes the final molt and sexual maturity.)
