Remarks: This is probably the most widely distributed pantropical tramp species, often becoming abundant in highly disturbed habitats. Its native distribution is uncertain but may in fact be the Afrotropical Region. The workers are narrow-bodied ants with very fast, erratic movements ("crazy ant"). They are generally non-aggressive and opportunistic. For building up large population densities they appear to require a resource of Coccoidea which they tend for harvesting their sugary excretions (WETTERER et al. 1999).
