How Insects Fly.

The article focuses on how flying insects stay airborne. According to French zoologist Antoine Magnan, the ability of bumblebees to fly defied all recognized physical principles and the secret of this kind of flight lies in swift wing beats. It says that fast wing beats are not produced separately by nerve stimulus. Professor Vincent B. Wigglesworth believes that midges are automatic flying machines. He adds that the fruit fly, drosophila, beats its wings 250 times per second.
