Flies are not a topic I was particularly interested in — until recently. In fact, I consider this insect little more than a disease-peddling annoyance. However, after perusing an article on how time moves slower for flies, I followed the research trail to this startling conclusion: Flies avoid swatters because they are adept and calculating.  

In fact, with a brain the size of a poppy seed, the fly can outmaneuver the biggest and brightest among us, pulling off an escape in less than 1/10 of a second. This bane of summer barbeques and outdoor picnics flitting over the potato salad and hot dogs is not simply a pesky pest but an amazing aerodynamic machine. 

A fly’s visual system is the fastest of any known organism. Its legs literally perform “a ballet” of sorts to reposition its body away from a threat. Even more than that, the fly can take off in any direction, regardless of how its body is aligned, using all-around vision. Its tiny brain can rapidly process sensory information and calculate not only its position but the position of the moving fly swatter.

And about that article on how time moves slower for flies?  Well, I learned that a fly’s concept of time is different than ours providing yet another reason they can dodge the swatter. Dr. Andrew Jackson, a researcher at Trinity College Dublin, says that flies “perceive light flickering up to four times faster than we can ... seeing everything in slow motion.” 

Co-researcher and professor Graeme Ruxton of the University of St. Andrews in Scotland, puts it this way: “Flies might not be deep thinkers, but they can make good decisions very quickly.”  (View the article “Flies Are Hard to Catch Because Time Moves Slower For Them” at http://www.businessinsider.com/s?q=Flies+are+hard+to+catch+because+time+moves+slower+for+them%2C+Rosa+Silverman
