Amblyopone oregonensis - Dracula Ants
Amblyopone is an ancient group of predaceous ants found worldwide. These subterranean ants have elongate mandibles and a characteristic broad posterior attachment of the petiole. Amblyopone ants are specialist predators of geophilomorph centipedes. Here a worker ant carries a centipede it has paralyzed back to her nest.
