In Australia, large Australian ant species are known to cohabit with small ant species, because the smaller ants pose no threat to the larger ants’ nest or the food sources, but they won’t tolerate medium-sized ants as they pose more of a threat. So this is not an unusual arrangement. Meat Ant colonies may be made up of a number of nests, sometimes spread over 500m and containing 60,000 or more ants, and they construct corridors between the nests and common food sources. The traffic alone can cause the corridors, but in addition they often clear grass and other impediments out of the way to make sure traffic is clear. As remarkable as it may seem, the deep pathways are solely the work of the ants.
