english: And it turns out that the insects flap their wings in a very clever way, at a very high angle of attack that creates a structure at the leading edge of the wing, a little tornado-like structure called a leading edge vortex, and it's that vortex that actually enables the wings to make enough force for the animal to stay in the air.
