Habitat/Ecology. Found in a broad range of habitats. Garden – colonies found under loose bark, closed up with earth, and in branches lying on the ground. Also collected from disturbed secondary forests and mangrove backforests. In mangroves, the ants were found nesting in a dead twig on a tree. Often observed and/or collected in urban settings, such as parks and inside household compounds or residences. Remarks. A globally widespread tropical tramp species with unknown native range. Commonly known as the ‘ghost ant’, alluding to its pale gaster and legs that contrast sharply with blackish brown head and mesosoma.
