Which insects go through complete metamorphosis?

• A. Cockroaches
• B. Moths & Fleas, Flies & Beetles, Bees & Wasps, Ants
• C. Bedbugs
• D. Silverfish

Answer: (B)

Complete metamorphosis, or holometabolism, means an insect goes through four distinct life stages—egg, larva, pupa, and adult—with each stage looking very different from the others. This pattern is found in moths, fleas, flies, beetles, and the bees, wasps, and ants. That collection covers the major groups that all share the holometabolous life cycle, so it best fits the concept being tested. Cockroaches undergo incomplete metamorphosis, with nymphs that resemble smaller adults and no pupal stage. Bedbugs and silverfish also do not show complete metamorphosis; they have stages that resemble adults or only gradual development without a true pupal phase.
