The Yellow Crazy Ant has the dubious distinction of being among the 100 worst invasive species in the world (IUCN/SSC Invasive Species Specialist Group). Its distribution has been expanded by human commerce, so that it is now widespread in tropical and subtropical regions of the globe. It is a well-known pest species, because it protects aphids and coccids which injure tropical crops.
