Argentine ant concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily take over the space. Austrian entomologist Gustav L. Mayr identified the first specimens of "Hypoclinea humilis" in the vicinity of Buenos Aires, Argentina in 1866. This species was shortly transferred to the genus "Iridomyrmex", and finally to "Linepithema" in the early 1990s. The native range of Argentine
Little black ant Little black ant The little black ant ("Monomorium minimum") is a species of ant native to North America. 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.
