Habitat/Ecology. This infamous invasive pest is mostly associated with areas of or close to human disturbance in Singapore, such as parks in semi-urban settings and urban residential areas. The ants are also common in young secondary forest fragments and at forest edges, for example waste woodlands and abandoned plantation secondary forests. The species appears tolerant of a broad range of different environment stressors, and has been collected from inland forest fragments, swamp forest, even mangroves.

Remarks. A well-known widespread global tramp species spread by human commerce and often ubiquitous in heavily disturbed environments, the earliest known record of P. longicornis in Singapore is a specimen in the BMNH dated back to 1931 ( Wetterer 2008).
