Amazing Australian ants

There are a number of rituals that go hand in hand with growing up in Australia. It goes without saying that in getting out of the wading pool as a kid (before water restrictions of course), there were bound to be European honey bees gathering pollen and nectar in the clover. It was Murphy’s Law that you would stand on one with bare feet or get one caught in your thongs as you ran across the lawn. The resultant sting was extremely painful and the knowledge that in stinging you the bee has, in effect, ripped its own insides out and will soon die was of small comfort to distraught children.

Neighbourhood cricket on the road (remove wicket and players in the event of a car), falling out of trees and buying firecrackers at the local milk-bar were all great fun for those of us of a certain age.

Another rite of Australian childhood is to be stung by a Bull ant or Jumping Jack. This genus of ants numbers around 90 species, and almost all are endemic to Australia. These ants have extremely good eyesight and will come out to meet what they see as threats to the colony they are defending.

Often the nest is fairly well hidden and one sure fire way of finding out you have a nest of these ants is an inadvertent drive-over with the lawnmower. This usually serves to enrage the inhabitants, who will spill out to defend the colony to the death. Bull ants and Jumping Jacks possess powerful venom, and also an impressive pair of mandibles or jaws. These jaws are used to grab the offending finger, leg, ankle, knee or toe while the sting at the end of the abdomen is injected into the skin - sometimes multiple times.  Note that a small percentage of the population can experience an allergic reaction to a sting from ants in this genus, and you should seek medical advice in such an event.

These amazing Australian ants were captured in May Gibbs’ Snugglepot and Cuddlepie along with other Australian wildlife such as goannas, snakes and kookaburras. Bull ants and Jumping Jacks are to be admired for their tenacity and also undertake a great job in cleaning up the environment. The female workers collect live and dead insects to take back to the colony to feed the young.
