Which insect has order Coleoptera and chewing mouthparts?

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

Answer: (C)

Beetles (order Coleoptera) are defined by having chewing mouthparts and front wings modified into hard covers called elytra that protect the hind wings. The insect that fits this combination is the Western corn rootworm, a beetle whose adults use chewing mandibles to eat plant material and whose larvae feed on corn roots. Water striders have piercing-sucking mouthparts as true bugs; white-lined sphinx moths belong to Lepidoptera and use a long siphoning proboscis; yellowjackets are Hymenoptera with chewing mouthparts but not Coleoptera. So the Western corn rootworm best matches both the order and the chewing mouthparts described.
