Meat ant a number of dead or alive animals, including metamorphic crucifix toads, snakes, lizards, and birds. On some occasions, swarms of workers have been found on dead foxes. 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. The collection of guano by any Australian
Red harvester ant the nest as a result of an increase in successful returning foragers. Relative abundance of food available is gauged by the average time spent foraging per seed, rather than the distance traveled to find each seed. Foragers take less time when food is more abundant. Faster foraging signals faster rates of outgoing foragers, maximizing the harvest of food relative to the abundance in the area. Seeds are used as a source of water for ants, and are often kept in the nest for a few months to several years. Interspecies competition exists between harvester ant populations, presenting challenges to successful
