Which order is described as true bugs with two membranous wings and piercing-sucking mouthparts?

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

Answer: (A)

Think about what defines true bugs: mouthparts built for piercing and sucking fluids. Hemiptera are the true bugs that fit this description, and their wings typically show a front pair that is partly hardened and partly membranous (the hemelytra) with the hind wings being membranous. This combination of piercing-sucking mouthparts and the characteristic wing arrangement is what identifies them as Hemiptera. Diptera have a single pair of wings and halteres, not two membranous wings; Lepidoptera have scaled wings and mouthparts for siphoning or chewing; Coleoptera have hard forewings (elytra) and chewing mouthparts.
