Honey Bee (Apis mellifera) 

As well as colonies in domestic apiaries, there are also feral colonies of honey bees in Australia. These can present a problem in some drier areas, where they congregate in hundreds or even thousands around sources of water. They form large colonies and will attack in large numbers if disturbed, although each bee is only capable of stinging once. Allergy to bee sting is common, and fatalities have occurred as a result of anaphylaxis.
