Ant nest beetle 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 species. Their pygidial glands
Jack jumper ant or cannot be carried out, known as the nest-site limitation hypothesis. Some queens could even try to return to their nests that they came from after nuptial flight, but end in another nest, in association that nests nearby will be similar to the queens birth nest. The jack jumper ant genome is contained on a single pair of chromosomes (males have just one chromosome, as they are haploid). This is the lowest number known (indeed possible) for any animal, a number shared with the parasitic roundworm "Parascaris equorum univalens". Jack jumper ants are taxonomically discussed as a single biological species
