Like something out of science fiction the fruiting body of Cordycepts erupts from the ant’s head. It can take three weeks to grow and when finished the deadly spores will burst from its tip. Then any ant in the vicinity will be in serious risk of death. The fungus is so virulent it can wipe out whole colonies of ants. It’s not just ants that fall victim to this killer. There are literally thousands of different types of cordiceps fungi and remarkably each specializes on just one species.
