When it comes to sneakiness, it is difficult to find a better practitioner than the queen of the Ravoux’s slavemaker ant. 

This European species of ant is known for its queen will faking her death, thus enticing ants from another colony to drag her back to their colony. Once inside, the queen seeks out that colony’s queen and assassinates her. Once that is accomplished, she steals the pheromones of the dead queen, making the other ants believe she is the one who actually belongs there.

Having thus supplanted the rightful queen, the usurper sets to work overrunning the colony with her own offspring, truly turning the colony into her own.
