Solenopsis geminata is an ant species from the Myrmicinae subfamily. The scientific name of the species was first validly published in 1804 by Fabricius.

Southern fire ant is a species adapted for cooperative living, with a sophisticated social structure organized around a single reproducing queen and varying castes of workers. This species exhibits an aggressive defense mechanism, emitting a sting that delivers a painful venom to deter predators. With a diet that includes proteins and sugars, southern fire ant forage efficiently, utilizing pheromone trails for their scavenging activities, highlighting their advanced communication systems.

Solenopsis molesta, also known as thief ants , get their names from their habit of nesting close to other ant nests, from which they steal food. They are also called grease ants because they are attracted to grease. Nuptial flight in this species occur from late July through early fall.

The red Imported Fire Ant( Solenopsis invicta ) is native to central South America. These aggressive ants can pose a serious threat to the health of humans, plants, and animals. The worker ants can sting their enemies repeatedly, unlike honeybee for once, and attack anything that disturbs them. In order to get honeydew easily, they farm aphids on plants, which are also harmful to plants. The red Imported Fire Ant cause billions of loss annually in the US.

Argentine ants are unable to dig deep nests so they tend to take up residence in the cracks of concrete, wooden floorboards, and even human belongings. They may also make a home in shallow leaf litter. Researchers have discovered three "supercolonies" of these ants, genetically related on three different continents, with the one in Europe spanning 6,000 km.
