Habitat/Ecology. This species is associated mostly with both mature and young secondary habitats at varying levels of disturbance in Singapore. These include swamp forest, mangroves, native-dominated, abandoned plantation and waste woodland secondary forests. Individual foragers are typically collected from tree trunks, while both alates and workers have been collected using malaise traps from disturbed secondary forest fragments in semi-urban settings. While considered arboreal, this species has been found nesting in unconventional places, e.g. in hollows of PVC or metal pipes - parts of artifical infrastructures such as malaise or leaf litter traps.
