Jack
jumper ant
Species:
Myrmecia pilosula
Known as the tigers of the ant world, jack jumper ants are aggressive and potentially deadly, killing on average one person every four years in Tasmania. Their sting releases venom that, in some people, can cause anaphylaxis, a life-threatening allergic reaction. Australia has about 90 different species of bulldog ant, as Myrmecia ants are known commonly, and all are armed with powerful stingers. But in Tasmania it is M. pilosula that poses the most significant threat, because it is common in suburban areas, and Tasmanians love being outdoors.
