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
Fire ant takes care of regular tasks (the main tasks in a colony are caring for the eggs/larvae/pupae, cleaning the nest, and foraging for food). However, "Solenopsis daguerrei" colonies contain no workers, as they are considered social parasites. Although most fire ant species do not bother people and are not invasive, "Solenopsis invicta", known in the United States as the red imported fire ant (or RIFA) is an invasive pest in many areas of the world, notably the United States, Australia, China and Taiwan. The RIFA was believed to have been accidentally introduced to these countries via shipping crates, particularly with Australia
