This video depicts the escape of a fruit fly, Drosophila melanogaster, in response to a black disk approaching from the right-hand side of the frame (left in one video). Within a tenth of a scond of spotting the disk, the fly begins leg and body motions that prepare it to take off away from the threat, regardless of its initial orientation.

Whenever we would get a few of these buggers in the house, they would be easy to spot, but, upon trying to smash em, they would seem to disappear before my eyes. This vid explains it all, now I know how to smash em.
