Habitat/Ecology. This species is associated mostly with old or mature secondary forests, as well as young secondary habitats such as Adinandra belukar dominated forest in Singapore. Both alates (males and queens) and workers have been collected, the former in great abundance, using malaise traps in swamp forest. The ants can also be found in disturbed secondary forest fragments in urban or semi-urban settings.
