I just happened across a great quote from Dave Barry and a related link. It has to do with the decapitating phroid fly, which has been imported into Florida in an attempt to control the population of fire ants.
How a phorid fly controls fire ants is, first the female phorid fly swoops in on a fire ant and, in less than a tenth of a second, injects an egg into the ant's midsection. When the egg hatches, the maggot crawls up inside the ant, and - here is the good part - eats the entire contents of the ant's head. This poses a serious medical problem for the ant, which, after walking around for a couple of weeks with its insides being eaten, has its head actually fall off. Meanwhile, inside the detached head, the maggot turns into a fly, and, when it's ready, crawls out and goes looking for more ants.
Dave, who certainly likes commas, then references a url which appears to have been a broken link. But I searched and found the new location here.
The video, which has a soundtrack of wild, jungle-style drum music, shows female flies zipping around fire ants like tiny fighter planes, giving the ants FITS. The video also shows how, when a fly isn't fast enough, it gets turned into Purina Ant Chow.
Gawd -- I just crack me up!
