Details about map content are available here.


Formica argentea is a medium-sized black or brown ant of the fusca group that typically has a silver sheen noticeable on sunny days (Lupertazzi and Alpert 2012). It is found in North America in southern Canada (Quebec east to British Columbia) and south through the US (SC, OH, IL, IA, SD, NM, AZ and CA) (Klotz et al. 2008). See Lupertazzi and Alpert (2012) for a North American distribution map.

This species is found in open habitats, including pastures and disturbed prairies; it nests in soil (nests are inconspicuous), and is a scavenger and oportunistic predator (AntWeb 2012). It is often attacked by ants in the genus Polyergus (Amazon ants) and is frequently a host for P. breviceps{ (Wild 2012)
