What are the two types of insect metamorphosis?

• A. Gradual metamorphosis and complete metamorphosis.
• B. Partial metamorphosis and total metamorphosis.
• C. Simple metamorphosis and complex metamorphosis.
• D. Direct metamorphosis and indirect metamorphosis.

Answer: (A)

Two patterns describe how insects change as they grow: gradual metamorphosis and complete metamorphosis. In gradual metamorphosis, the young (nymphs) resemble the adults and molt through several stages without a pupal stage. Grasshoppers, crickets, and many true bugs are examples. In complete metamorphosis, there are four life stages—egg, larva, pupa, and adult—the larva and adult look very different, and a pupal stage is a time of major transformation. Beetles, butterflies and moths, bees, and flies follow this pattern. These are the standard ways scientists categorize insect development, which is why this pair is the correct answer. The other terms don’t represent the widely recognized categories.
