Why is it so hard to swat a fly??
It’s coz the brains of flies are wired to avoid the swatter. According to U.S. researchers who made their fly study results known last Thursday, at the mere hint of a threat, the flies adjust their pre-flight stance to flee in the opposite direction. Of course, you, the swatter is like “what?? where did it go??” Michael Dickinson of the California Institute of Technology explained, “These movements are made very rapidly, within about 200 milliseconds, but within that time the animal determines where the threat is coming from and activates an appropriate set of movements to position its legs and wings.”
Apparently, in response to a threat from the front, the fly moves its middle legs forward, leans back and raises its back legs for a backward takeoff. If the threat is from the side, the fly leans the other way before takeoff. Mr. Dickinson, whose research appears in the journal Current Biology, further explained: “This illustrates how rapidly the fly’s brain can process sensory information into an appropriate motor response.” So you, the swatter, not swat at the fly’s starting position, but instead, aim for the escape route.
