Ah, Australians. First they introduced cane toads to hunt the greyback cane beetle pests - but the toads turned out to be a much bigger pest and their toxic kill many native predators and farm animals.
Now, there's a proposal to control the cane toad population by introducing yet another species to battle it: meat-eating ants.
Omnivorous meat ants are native to Australia and reportedly nests in groups of more than 60,000. Professor Rick Shine said that meat ants attack and eat toads. "The ants are moving through these open areas, scavenging for dead insects and so on. If they encounter a baby toads it obviously seems like an appropriate lunch and jump on it. "
