Polistes fuscatus use oophagy as a method to establish a dominance hierarchy; dominant females will eat the eggs of subordinate females such that they no longer produce eggs, possibly due to the unnecessary expenditure of energy and resources. This behavior has also been observed in some bee species. Such bee species include Xylocopa sulcatipes and Bombus ruderatus, where queen bees will eat larvae deposited by workers or eject them from the nest in order to maintain dominance over the colony.
