The meat ant is the only known ant in Australia that feeds on fresh guano. The collection of guano by a nearby meat ant colony shows the opportunistic nature of the species. Observations show that trails of workers in groups of two to four were found collecting the guano under an active bat roost within an abandoned mine and proceeded to return it to the nest.

Green-head ant they prefer. This suggests that the cost of moving to a suitable nesting site outweighs the benefits of moving to a larger rock. A large expenditure of energy is required for a move: scouts must first find a suitable site, brood must be transported safely, and the colony is exposed to an increased risk of predation. Nest abandonment by the green-head ant varies, but peaks during summer. Like other temperate species, activity in colonies is greatly reduced during the colder months, which may be the reason there is a high proportion of nest abandonment during summer.
