Which of the following is true about Diptera?

• A. Diptera means two wings
• B. Diptera means four wings
• C. Diptera means no wings
• D. Diptera means three wings

Answer: (A)

Two wings define Diptera. The name comes from Greek di- meaning two and ptera meaning wings, pointing to the fact that these insects have one functional pair of wings used for flight. The second pair isn’t true wings—it’s reduced to halteres, small balancing organs that help with stability in the air. That combination—one pair of wings with the hind pair transformed into halteres—is what sets Diptera apart from insects with four wings, wingless insects, or any imaginary three-wing configuration.
