Sep 2, 2022 · The ant fauna of Australia is especially large and diverse. World-wide there are about 300 genera and about 15,000 described species and subspecies of ants. Australia is currently known to have representatives of about 100 genera and 1300 described species and subspecies. While the numbers of Australian genera are unlikely to increase ...

The bulldog ant Myrmecia brevinoda is the largest ant in the world in terms of average worker size [1]. The ant fauna of Australia is large and diverse. As of 1999, Australia and its external territories represent 1,275 described taxa (subspecies included) divided into 103 genera and 10 subfamilies. [2]
Ants are probably the most common insects encountered by humans. There are around 15,000 different species of ants worldwide. There are 1,275 Australian ant species described, but this could double with further research. Most species of Australian ants are found only in Australia.
Fast Facts. Ants are highly social insects and live in colonies ranging in size from a few tens of individuals to over a million individuals, depending on species. Colonies can exist for several years, to decades in some cases. Some colonies remain in one place, while others are mobile armies moving from one food source to another.

Bull ants collect nectar and other plant juices, as well as animal prey, which are carried back to the nest.
Bull ant nests are usually underground and often have hidden or small entrances. The nests can extend several metres below the ground. They attack intruders of any size that come too close to their nest. Bull ants also have well-developed vision and will follow or even chase an intruder a good distance from the nest. Usually the sight of large aggr...
Several species have no colony workers. Instead, a raiding queen invades the nest of another species, kills the resident queen and takes over the colony.
These ants can deliver painful stings and are aggressive. An ice pack or commercially available spray may be used to relieve the pain of the sting. If there is evidence of an allergic reaction, medical attention should be sought.
Ant plants. There is even an ant species that has a symbiotic relationship with an epiphytic plant called an ant-house plant (Myrmecodia beccarii). The ant provides a physical defence against plant eating invaders and the plant provides housing and, possibly, food for the ant. A third species is also part of this symbiosis.

Aug 5, 2022 · It shows an estimate of the number of ant species living in each square (called the species richness). They also created a map showing the number of ant species with very small ranges in each square (called the species rarity). In general, species with small ranges are particularly vulnerable to environmental changes.
