Ant nest beetle can produce explosive secretions, giving them the other name of flanged bombardier beetles although they are not particularly close relatives of the typical bombardier beetles (Brachininae). Very little is known about the immature stages of ant nest beetles. Most appear to live in ant nests in their early stages of life. Although many are facultative or obligate myrmecophiles, most do not appear like ants (i.e. myrmecomorphic) and unlike in the case of myrmecophilous larval Lycaenidae, there appears to be no benefit gained by the ants in this association. Many species follow the trails of worker ants of specific species. Glandular
Ant spider and use their mimicry to enter and leave the nest unmolested (if the ants detected them as intruders they would mass to repel and perhaps kill them). The spiders walk on only the three rear pairs of legs, and if they encounter an ant during their forays into the nest territory, they touch their front legs to the ant's antennae in the same way as another ant would with its own antennae. If they have already captured an ant, they then offer that towards the challenging ant, which inspects it and behaves towards the spider as if it were another
