Which metamorphosis type do cockroaches undergo?

Which metamorphosis type do cockroaches undergo?

• A. Complete metamorphosis.
• B. Incomplete metamorphosis.
• C. No metamorphosis.
• D. Mixed metamorphosis.

Answer: (B)

Incomplete metamorphosis, also called gradual metamorphosis, is characterized by a life cycle of egg, nymph, and adult. The nymphs resemble small adults and molt as they grow, and there is no pupal stage. Cockroaches follow this pattern, developing into adults through multiple molts without a pupal phase. This differs from complete metamorphosis, where a distinct pupal stage sits between larva and adult and the immature forms look very different from the adults. Some insects show ametabolous development, with little to no change as they mature. Thus, cockroaches exhibit incomplete metamorphosis.
