Habitat/Ecology. This species seems mostly associated with primary or old/mature secondary forests in Singapore, including dry secondary forest adjacent to swamp forest. It is considered subterranean, and individuals could be found in soil at bases of trees, under logs, inside rotting logs and termite mounds, suggesting a possible termitophagous nature of this species. An alate queen was collected from a malaise trap set up in mangroves.
