The wings of a housefly beat hundreds of times each second during flight.

The longer version

Wing muscles in a housefly do not contract once per nerve signal the way ours do. The thorax works like a resonating box: one set of muscles deforms it and springs it back, so the wings snap up and down in a self-sustaining rhythm that requires very little repeated signalling.

Nerve impulses mostly set tempo and steering, while small muscles adjust wing angle for turning. Short wings also lose less momentum at each reversal, making rapid switching possible. The high beat rate produces the familiar buzzing pitch and explains why the animal can dart sideways and leave almost instantly.
