Summary:
When startled by predators, tiny fruit flies respond like fighter jets, employing screaming-fast banked turns to evade attacks. In the midst of a banked turn, the flies can roll on their sides 90 degrees or more, almost flying upside down at times. Researchers used an array of high-speed video cameras operating at 7,500 frames a second to capture the wing and body motion of flies after they encountered a looming image of an approaching predator.
