Formica archboldi is a species of ant in the family Formicidae, hence its common name, Skull-collecting Ant. They are known for their unusual behavior, which includes the collection and storage of Odontomachus (trap-jaw) ant skulls.
Formica archboldi ants store these severed ant heads in their nests. Formica archboldi have odors that are chemically similar to the odors of the trap-jaw ants, which might allow Formica ants to disguise themselves among trap-jaw ants. Formica ants immobilize trap-jaw ants by spraying formic acid, then drag them into their nest, and dismember them.
