Pharaoh ant new nest is formed, queens are not a necessity; workers can raise new queens after finding a suitable nest site. In pharaoh ant colonies new males and queen ants can be produced when the existing fertile queen is removed. When queens are absent, the workers in the nest can do two things: either rear existing sexual larvae or transport sexual larvae from other bud nests or from the main nest to its own nest. However, when there are fertile queens still within the nest, the worker ants will cannibalize the sexual larvae and will either reject or consume sexual larvae
Ant mimicry call of ants so they can integrate themselves into the nest. In "A. dentatis" the tubercles release the mimicking pheromone which elicits "A. caprensis" to care for the mimics as they would their own brood. In these relationships worker ants give the same preference to the Lycaenid's as they do to their own brood, demonstrating that chemical signals produced by the mimic are indistinguishable to the ant. This process is also used by larvae of the European Lycaenid species "Phengaris rebeli" which live in the nests of "Myrmica" ants and feed on their ant brood. Wasmannian mimicry occurs when two
