Which insect holds the record for the fastest wing beats?

• A. A midge in the genus Forcipomyia
• B. A dragonfly
• C. A bee
• D. A mosquito

Answer: (A)

Wingbeat rate in insects is closely tied to body size and the flight muscle system. The fastest wing oscillations come from very small insects that use specialized indirect flight muscles to drive rapid thorax vibrations. In Forcipomyia midges, these tiny wings are driven by asynchronous indirect flight muscles, which lets the thorax vibrate at incredibly high frequencies and the wings to flap thousands of times per second. The result is an extraordinary wingbeat rate that dwarfs larger insects. Dragonflies rely on larger wings and more powerful, but slower, wing strokes (their flapping is in the tens of cycles per second), giving them exceptional maneuverability rather than record speeds. Bees flap around a few hundred times per second, which is fast for a bee but still far below the midges. Mosquitoes flap faster than large insects but not nearly at the extreme rates seen in Forcipomyia midges. So the insect with the record for the fastest wing beats is the midge in the genus Forcipomyia, due to its tiny size and the use of indirect flight muscles that enable extremely high-frequency wing flapping.
