Which insect has chewing mouthparts and belongs to Hymenoptera?

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

Answer: (A)

Chewing mouthparts are used to bite and chew solid food, and Hymenoptera includes wasps, bees, and ants with mandibles adapted for chewing. Among the insects listed, the yellowjacket is a wasp in Hymenoptera and has strong mandibles for biting and chewing prey and material. That combination—Hymenoptera identity and chewing mouthparts—makes it the best fit. The water strider belongs to a different order (Hemiptera) and has piercing-sucking mouthparts. The Western corn rootworm is a beetle (Coleoptera) with chewing mouthparts but not in Hymenoptera. The white-lined sphinx moth is a Lepidoptera with a siphoning proboscis, not chewing mouthparts. So the insect that has chewing mouthparts and belongs to Hymenoptera is the yellowjacket.
