, groups, and environments that determine whether an individual will benefit from a high rank. Dominant individuals in this case are known as queens and have the obvious advantage of performing reproduction and benefiting from all the tasks performed by their subordinates, the worker caste (foraging, nest maintenance, nest defense, brood care and thermal regulation). Female behavioral strategy: dominance helps females deal with the unusually high reproductive demands; they prevail in more social conflicts because they have more at stake in terms of fitness.

The energetic costs of defending territory, mates, and other resources can be very consuming and cause high-ranking individuals, who spend more time in these activities, to lose body mass over long periods of dominance. 29 Research has shown that removal of the queen from the colony allows the reestablishment of reproductive function in sub-dominant individuals. Workers additionally have been noted to display aggression towards males, claiming priority over the cells when males try to use them to place eggs. However, they may vary based on the situation and position of the individuals involved.
