High-speed video captures fruit fly escape maneuver
What does a tiny fruit fly have in common with an F-22 Raptor fighter jet? More than you might think if you’ve ever been amazed at how the little pests avoid the flyswatter. Scientists using video cameras to track a fly’s aerial maneuvers found that the insect employs astonishingly quick banked turns to evade predators, much like the ones executed by a fighter jet to elude an enemy.
The study, published yesterday in the journal Science, shows that fruit flies are able to change course in less than a hundredth of a second. The flies produced impressive escape responses, almost instantaneously rolling their bodies like a military jet in a banked turn to steer away. While executing the turn, the flies showed that they could roll on their sides by upwards of 90 degrees, sometimes flying almost upside down.
