This video shows one period of the dragonfly Libellula pulchella’s hovering motion. In real time the motion takes about 1/40 second; this video has been slowed down by a factor of about 100. Note that the fore and hind wings beat out of phase and that each of the four wings executes a feathering motion. [Download video]
