The following list of exotic ant species includes 27 species, plus the hybrid fire ant, Solenopsis X invicta. These introductions were from a variety of regions including Central and South America, Europe, Africa, Australia, and Asia. Much of this information is from Deyrup et al. (2000) and McGwynn (1999).
Clicking on a species name will lead to a page with further information and photographs of that species. Although species pages are at various levels of progress, most pages now have representative photographs of at least workers of the species. In addition to the photographs of ants taken by Joe MacGown at the Mississippi Entomological Museum (MEM), many photos are used, with permission, from AntWeb, a web site about ants of the world with amazing photos. Another site with photographs of ants is "Discover Life." The Discover Life site provides a list of North American ants with photos at "Kinds of Ants , Ants of North America Page". On each individual MEM species page, a link is provided (at the bottom of the page) for that species on both the AntWeb site and the Discover Life ant site. Additionally, many of the species found in this list can be identified using the identification keys found on this web site.
