‘Crazy ants’ invade southeastern U.S., displacing native species

Ants invade the southeastern U.S.

Invading Tawny “crazy ants” from South America are displacing native fire ants across the southeastern United States and could have a dramatic impact on the region’s ecosystem, according to a new study. Native to northern Argentina and southern Brazil, the tawny crazy ant (Nylanderia fulva) was formally identified in 2012. Often referred to as Raspberry crazy ants, scientists have officially dubbed them “Tawny crazy ants.”

Although Tawny crazy ants do not sting humans like fire ants, they are far more intrusive, establishing super-colonies that push out local ant and arthropod populations. Sometimes they even take over entire homes.
