A Note on Bee's
To my great joy the bumble bees are enjoying my broad bean flowers.
They have to move their wings 200 beats per second to generate lift, which 10 to 20 times the firing rate of their nervous system.
The trick is that the bee's wing muscles don't expand and contract so much as vibrate.
The nerve impulse twangs the muscle, like a piano chord, and vibrates the wing up and down a few times until the next belt of impulse.
