About Formica archboldi Smith, 1944
Formica archboldi is a species of ant that belongs to the family Formicidae. This ant species displays unusual behavior: it collects and stores the skulls of Odontomachus ants, more commonly known as trap-jaw ants, and keeps these severed ant heads inside its nests. The chemical odor of Formica archboldi is similar to that of trap-jaw ants, and this similarity may allow F. archboldi ants to disguise themselves among the trap-jaw ants. To hunt trap-jaw ants, F. archboldi ants first immobilize their targets by spraying formic acid. They then drag the immobilized trap-jaw ants back to their nests and dismember them.
