A slow-motion video of a dragonfly taking off from the end of a green stick or branch. All four wings initially push downward at once to lift off of the branch. After liftoff, the front pair and back pair alternate, the front wings flapping downward as the back wings go upward and vice versa. The front edges of all four wings are rigid, but the surfaces of the wings flex and deflect as they move through the air.
