It is important to emphasize the distinctions between monogyny and polyandry, and monogyny and monogamy. Colonies of "A. flavissima" can rotate between polygyny (multiple queens) and monogyny (one queen). Under monogyny and monandry, the worker typically produces the males rather than the queen. Through evolution, polygyny may have arisen through monogyny. The mating system of monogyny is most common in ants, honeybees, and spiders. These colonies demonstrate monogyny through their mating habits. This model predicts that a male-biased sex ratio is required for monogyny to evolve. If females are unrelated, the costs would usually outweigh the benefits, and monogyny would result. In "R. fasciata", monogyny is said to be facultative. Generally, monogyny should prevail unless polygynous benefits outweigh the costs of shared reproduction.
