The food substance is given to the larvae. They digest and regurgitate it for the adults. This must happen because the adults have a very thin esophagus and cannot swallow large particles of food. The Argentine ant is one species among more than 175 known species of ants in California. Although Argentine ants seem no different from other ants, they are.
Argentine ants are social insects.
Argentine ants were accidentally imported by coffee shipments to New Orleans circa 1891. Since that time they have spread eastward into the Carolinas and as far south as Southern Florida and westward into Texas and California. Argentine ants are also located in Argentina, Brazil, Australia, and Africa. Usually ants of the same species, in different colonies, will fight each other. However, Argentine ants cooperate with each other.
