Meat ant within a colony is typically favoured as it improves access to forage, as workers deliver most of their food to the nest that is closest to any site they forage in. At any size, a meat ant nest always has a possibility of dying out in any year, but the site may be reoccupied by another colony. Hence, nests can be very old as suggested in one study. Some nests may never be reoccupied for unknown reasons. The regrowth of vegetation which shades the nest, soil damage or even a disease may wipe out a colony and leave the nest
Little black ant Workers may forage in households, but nest in soil mounds. It also tends aphids such as the soybean aphid ("Aphis glycines"), harvesting honeydew. During mid-summer the queens and males perform the nuptial flight, mating in midair. The males die shortly after. Each queen constructs a new nest, sheds its wings, and lays eggs. The development from egg to adult takes about a month. In a laboratory setting queens were found to live about one year and workers about four months.
