Ant nest beetle secretions on their antennae and body allow them to interact with ant workers. It is believed that the beetles use an acoustic mechanism to successfully imitate the sounds of an ant queen thus permitting them access to the nest without alarming the ants. The defensive bombardier behaviour is never used against ants. Males of some species are attracted to lights during some parts of the season and are thought to disperse from one ant nest to another. Males are thought to be short-lived. These beetles feed on ant eggs, larvae and adults by piercing their mandibles into the abdomen or
Slave-making ant slave-maker ant offspring. This is because "slaves can gain indirect fitness benefits by reducing parasite pressure on nearby host colonies, because these are often closely related to the slaves". Thus, the slave ants protect their native colonies from further raids by slave-maker ants. The reproductive behavior of slave-making ants usually consists in synchronous emergence of sexuals followed by a nuptial flight and the invasion of a host nest, but also in some cases females display a mating call around the natal nest to attract males and immediately after mating search for a host nest to usurp. Only one slave species
