Red Imported Fire Ant (Solenopsis invicta) The red imported fire ant (RIFA) is a small reddish brown ant from South America . There are six known species of fire ants (Solenopsis spp.) in the United States, three of which are found in Arizona. These three species are the southern fire ant (S. xyloni), and two species of desert fire ant (S. aurea and S. amblychila).
Fire ant is the common name for several species of ants in the genus Solenopsis. They are however only a minority in the genus, which includes over 200 species of Solenopsis worldwide.Solenopsis are stinging ants and most of their common names reflect this, for example, ginger ants and tropical fire ants.Many species also are called red ants because of their light brown colour, though species of ants in many other genera are similarly named for similar reasons.ire ants often attack small animals and can kill them. Unlike many other ants, which bite and then spray acid on the wound, fire ants bite only to get a grip and then sting (from the abdomen) and inject a toxic alkaloid venom called Solenopsin, a compound from the class of piperidines.
