The meat ant (Iridomyrmex purpureus), also known as the gravel ant or southern meat ant, is a species of ant endemic to Australia. A member of the genus Iridomyrmex in the subfamily Dolichoderinae, it was described by British entomologist Frederick Smith in 1858. The meat ant is associated with many common names due to its appearance, nest-building behaviour and abundance, of which its specific name, purpureus, refers to its coloured appearance. It is among the best-known species of ant found throughout Australia; it occurs in almost all states and territories except for Tasmania. Its enormous distribution, aggression and ecological importance have made this ant a dominant species.
The meat ant is monomorphic (occurs in a particular form), although there is evidence that certain populations can be polymorphic. It is characterised by its dark-bluish body and red head. It is a medium to large species, measuring 6–12 mm (0.24–0.47 in). The workers and males are approximately the same sizes at 6–7 mm (0.24–0.28 in) and 8 mm (0.31 in), respectively. The queens are the largest and appear mostly black, measuring 12.7 mm (0.50 in). The iridescence in workers ranges from green or blue to plain green and purple, varying in different body parts and castes. Meat ants inhabit open and warm areas in large, oval-shaped mounds that are accompanied by many entrance holes. The nest area is always cleared of vegetation and covered with materials including gravel, pebbles and dead vegetation. They are also polydomous, where a colony may be established in a series of satellite nests connected by well-defined paths and trails. Satellite nests are constructed away from the main nest in nearby areas with valuable food sources so workers can exploit them.
Queens mate with a single male and colonies may have more than one queen until the workers arrive, where they both exhibit antagonism. It takes around one or two months for an individual egg to develop into an adult. Colonies range in size, varying between 11,000 individuals to over 300,000. The meat ant is a diurnal species (active throughout most of the day), especially when it is warm. It forages on trees and collects sweet substances such as honeydew and nectar, and also captures insects or collects the remains of animals. A number of predators eat these ants, including the short-beaked echidna (Tachyglossus aculeatus), numerous species of birds, blind snakes and spiders. This species is also a competitor of the banded sugar ant (Camponotus consobrinus). Wikipedia →

Possible
About 30% of wildlife watchers report a Southern Meat Ant sighting in Grampians National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 148 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February, June and November
In those months about 40% of wildlife watchers report a Southern Meat Ant in Grampians National Park on a given day, against under 5% in April and August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Southern Meat Ant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Southern Meat Ant sightings, Grampians National Park has the highest daily chance: about 30%. Next come Flinders Ranges National Park (Australia, about 20%) and Flinders Chase (Australia, about 20%).
Same family: Formicidae
The closest relatives of the Southern Meat Ant that you can see in Grampians National Park (family Formicidae, Ants) are Black-Scaped Bull Ant (about 40%), Jack Jumper Ant (about 40%) and Banded Sugar Ant (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Meat Ant is recorded against all the insects logged in Grampians National Park (42 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
