Ant colony Ant colony An ant colony is the basic unit around which ants organize their lifecycle. Ant colonies are eusocial, and are very much like those found in other social Hymenoptera, though the various groups of these developed sociality independently through convergent evolution. The typical colony consists of one or more egg-laying queens, a large number of sterile females (workers, soldiers) and, seasonally, a large number of winged sexual males and females. In order to establish new colonies, ants undertake nuptial flights that occur at species-characteristic times of the day. Swarms of the winged sexuals (known as alates) depart the nest
Green-head ant ants are unlikely to be invaded by other species, so nest invasions are an unlikely cause of nest vacation. The structural breakdown of a nest and competition with other neighbouring colonies is also unlikely, but a possible factor is the seasonal production of food sources and food competition. The green-head ant is a diurnal species that is active throughout the day, quickly foraging on either the ground or vegetation. They are scavengers, predators and seed-eaters, generally having a broad diet of animal material, insects, small arthropods, honeydew from sap-sucking insects and seeds. The workers usually prey on beetles, moths and
