United States



The following 664 valid species and subspecies of ants are known to occur in the United States. Ants from Hawaii are on a separate list. Unidentified and undescribed species will be added to this list as identifications are verified and taxonomic revisions are published. This species list is based upon the effort of many ant collectors as well as myrmecologists who have published on the taxonomy of United States ants.

Those who have specimen records that expand this list are encouraged to submit this information in the discussion section of the United States Ants web page. Please advise if any corrections are warranted.

An index of information about the Ants of the United States is found at the United States Regional Project page.
