New weapon turns fire ants into headless zombies - USATODAY.com
Fire ants are estimated to be costing the Texas economy as much as $1 billion annually, so the state is introducing the four species of the phorid fly, a natural predator of the fire ant, to keep their numbers in check. The fly lays eggs on the fire and that hatch, enter the ant, eat its brain, then emerge as adult flies when the ant's head falls off. The ant apparently spends two weeks wandering around as a zombie while the phorid maggot consumes its brain.
