Black Garden Ant Lat. “Lasius niger“

55213

The black garden ant (Lasius niger), also known as the common black ant, is a formicine ant, the type species of the subgenus Lasius, found all over Europe and in some parts of North America, South America, Asia and Australasia. The European species was split into two species; L. niger is found in open areas, while L. platythorax is found in forest habitats. It is monogynous, meaning colonies have a single queen.

Long-lived queens

Although worker ants live for a couple of months, queens typically survive for almost 15 years but there have been instances of queens living up to 29 years, the longest recorded lifespan for any eusocial insect. Understanding the basis for the greater longevity of queens has a bearing on the general unsolved problem in biology of the causes of aging. In the study of long-lived queen ants it was found that queens have a higher expression than genetically identical workers of genes involved in processing damaged macromolecules. Genes with higher expression included those that are necessary for repair of DNA damage (see DNA damage theory of aging) and genes involved in proteasome-mediated, ubiquitin-dependent, protein catabolic processes.

Mutualisms

Lasius niger removes predators such as ladybirds from the vicinity of black bean aphid thus keeping their “milch cows” safe. On a test plot of field beans (Vicia faba), plants without black bean aphids yielded an average of 56 seeds per plant, those with aphids and no ants yielded 17 seeds, and those with both ants and aphids averaged eight seeds per plant. Vicia faba also produces extrafloral nectaries that Lasius niger can feed from directly. The Plebejus argus butterfly lays eggs near nests of L. niger, forming a mutualistic relationship. This mutualistic relationship benefits the adult butterfly by reducing the need for parental investment. Once the eggs hatch, the ants chaperone the larvae, averting the attacks of predatory organisms like wasps and spiders as well as parasites. In return, the ants receive a saccharine secretion fortified with amino acids from an eversible gland on the larvae’s back. As first instar larvae prepare to pupate, the ants carry the larvae into their nests. Once the larvae become pupae, the ants continue to provide protection against predation and parasitism. The butterfly leaves the nest when it emerges in June.
