Nylanderia fulva, commonly known as the tawny crazy ant, is an invasive ant species native to South America that has become a significant pest in the southern United States. The species is characterized by its erratic, rapid movement patterns and ability to form enormous supercolonies with millions of workers. It was first reported in the continental United States in 1938 but only recognized as a serious pest in the 1990s in Florida and 2000s in Texas. The ant exhibits a unicolonial social structure in its invasive range, with interconnected nests showing no intraspecific aggression.
