Which insect does not undergo complete metamorphosis?

• A. Western Corn Rootworm
• B. Water Strider
• C. White-Lined Sphinx Moth
• D. Yellowjacket

Answer: (B)

Insects are categorized by how they transform during development. In incomplete metamorphosis, the young (nymphs) resemble smaller versions of the adults and molt through several stages without a pupal stage. Water striders are true bugs (Hemiptera) and follow this pattern, so their nymphs look like tiny adults and no pupal stage occurs. The other insects listed undergo complete metamorphosis, meaning they have distinct life stages: egg, larva, pupa, and adult, with the larva and adult looking very different and a pupal stage between them. A beetle starts as a larva (grub), a moth as a caterpillar, and a wasp as a larva and then a pupa before becoming adults. So, the insect that does not undergo complete metamorphosis is the Water Strider.
