I can find info on how bumblebees fly. But nothing mentions how they can be so nimble. Without a tail, what mechanism allows them to manage such quick changes of direction?

I've seen them float stationary, then take off, then do a complete 180 with no discernable slowdown. How do they do it?

Most insects (bumblebees included) don't simply flap their wings up and down. Each stroke (and both the up and down strokes) can be angled and turned depending on what they are trying to accomplish. Additionally they flap very fast. This combination of speed and variety of wing strokes allow many insects to change direction rapidly.

How fast are their wings? Synchronous flight muscles beat at 5 to 200 hertz (Hz), in those with asynchronous flight muscles, wing beat frequency may exceed 1000 Hz.
