Ant nest beetle Subtribe Paussina Subtribe Pentaplatarthrina Ant nest beetle Ant nest beetles (subfamily Paussinae) or paussines, some members of which are known also as flanged bombardier beetles, are a large subfamily within the ground beetles (Carabidae). The tribes Metriini, Ozaenini, Paussini and Protopaussini are included in the subfamily. Rarely seen, most Paussinae are obligate or facultative myrmecophiles, living within the nests of ants, predatory on ant larvae and workers. Many have elaborate antennal structures and body parts flattened. Paussines are moderate sized (6–20 mm), characterised by glandular hairs that produce secretions attractive to ants and by the odd antennal structures of many
Ant from other social insects including other ants. Some species specialise in preying on termites ("Megaponera" and "Termitopone") while a few Cerapachyinae prey on other ants. Some termites, including "Nasutitermes corniger", form associations with certain ant species to keep away predatory ant species. The tropical wasp "Mischocyttarus drewseni" coats the pedicel of its nest with an ant-repellent chemical. It is suggested that many tropical wasps may build their nests in trees and cover them to protect themselves from ants. Other wasps, such as "A. multipicta", defend against ants by blasting them off the nest with bursts of wing buzzing. Stingless bees
