Camponotus sexguttatus

This widespread species is quite variable, as indicated by the large number of synonymized names and subspecies (see the bottom of the taxobox to the right).

Distribution
Native range from Argentina to Nicaragua, plus the Caribbean. It has also become established in Florida and Hawaii.

This taxon was described from Antilles. It is also found in Ecuador, Brazil, Bolivia, Uruguay, Colombia, Peru, Argentina, Suriname, Paraguay, French Guiana, Guyana, Honduras, Nicaragua, Panama, Costa Rica, United States, Dominican Republic, Puerto Rico, Saint Lucia and Barbados.

Florida
Camponotus sexguttatus has been collected a number of times in Florida but is apparently a recent arrival. The earliest collection records are from 1993. Nests were found in saw grass stems at the edge of marshy areas (Deyrup et al. 2000). A nest was also discovered in an exotic acacia species in Walt Disney World's Animal Kingdom (Wetterer and Wetterer 2003).
