Which order includes sawflies, wasps, ants, and bees, with chewing mouthparts and four membranous wings?

• A. Hymenoptera
• B. Diptera
• C. Lepidoptera
• D. Coleoptera

Answer: (A)

This question tests your ability to identify an insect order by wing type and mouthparts. Sawflies, wasps, ants, and bees all belong to Hymenoptera, the group known for chewing mouthparts and two pairs of membranous wings (four wings total). In flight, the forewings and hind wings are often linked together by tiny hooks called hamuli, so they move as a single unit. Many members also have a constricted waist between the thorax and abdomen, which is common in wasps, bees, and ants, though sawflies lack this narrow waist. The other orders don’t match this specific combination: Diptera have only one pair of wings; Lepidoptera have scaled wings and mouthparts adapted for sucking; Coleoptera have hardened front wings (elytra) over the hind wings and different mouthpart adaptations.
