>From the 2002 Southern edition of the Old Farmers' Almanac: FIRE-ANT ALARM
After years of trying to get rid of those nasty, sometimes-fatal fire ants, scientists think they have a solution imported from Argentina. The pinhead-size phorid fly, also known as the decapitating fly, injects an egg into the ant and takes off. The egg hatches into a maggot, which slithers into the ant's head and feeds on juices there. The rest--well, you can imagine. These flies are slowly infiltrating fire-ant strongolds in seven southern states without any apparent danger to the rest of the ecosystem.
