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
Pharaoh ant been introduced. It also helps prevent ants from concentrating on an undesirable trail. Thus, the repellant pheromone makes the pharaoh ant a particularly efficient forager. Despite their extreme importance, there is an adaptive value to using pheromones sparingly, as it streamlines communication during important decision-making situations, such as a nest migration. Pharaoh ants use a positive feedback system of foraging. Each morning, scouts will search for food. When one finds it, it will instantly return to the nest. This causes several ants to follow the successful scout’s trail back to the food source. Soon, a large group will be upon
