Stumbled Upon

Ravoux's slavemaker ant (Epimyrma ravouxi) is a species of ant in the family Formicidae. It is endemic to France. The queen will fake death to entice ants from another colony to drag her back to their nest, where she awakens and kills the nest's original queen. She will then wrap herself in the dead queen's carapace, and will begin producing eggs. The slavemaker ants then overrun the colony and then find a new colony to take over.
