The little black ant (Monomorium minimum) is a species of ant native to North America.[1] It is a shiny black color, the workers about 1 to 2 mm long and the queens 4 to 5 mm long. It is a monomorphic species, with only one caste of worker, and polygyne, meaning a nest may have more than one queen. A colony is usually moderately sized with only a few thousand workers.
Monomorium minimum are scavengers that will consume anything from bird droppings to dead insects. They are predators of codling moth larvae, and also of fall webworm.[2] [3] Workers may forage in households, but nest in soil mounds. They harvest the honeydew of aphids such as the soybean aphid (Aphis glycines).[4]
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.
