Solenopsis geminata is native to Central and South America, including the Caribbean islands, but has since spread throughout the tropics by human means. It is an invasive species with a world-wide distribution even greater than that of other invasive fire ant species such as Solenopsis invicta (red imported fire ant).
Solenopsis invicta is the most famous species in this genus, especially in the US, however several other species are similarly dangerous and invasive, such as Solenopsis geminata, which has invaded most of the tropical countries, wreaking havoc in medical systems especially in unprepared countries and islands.

The also highly invasive red imported fire ant (Solenopsis invicta) and Solenopsis geminata additionally use classic mating flights, thus using three primary modes of dispersal. [5] [6] Out of some 14,000 described ant species, supercolonialism is found in less than 1% of all ants. [2]
Solenopsis invicta, the fire ant, or red imported fire ant (RIFA), is a species of ant native to South America. A member of the genus Solenopsis in the subfamily Myrmicinae , it was described by Swiss entomologist Felix Santschi as a variant of S. saevissima in 1916.
This is a list of valid species of the myrmicine genus Solenopsis (fire ants). There are over 200 species in this genus. ... Solenopsis geminata (Fabricius, 1804 ...
Fire ants, Solenopsis spp., are unique in having a venom sac containing piperidine alkaloids. [100] Their stings are painful and can be dangerous to hypersensitive people. [101] Formicine ants secrete a poison from their glands, made mainly of formic acid. [102] A weaver ant in fighting position, mandibles wide open
In the 1930s, colonies were accidentally introduced into the United States through the seaport of Mobile, Alabama.Despite earlier views that cargo ships from Brazil docking at Mobile unloaded goods infested with the ants, [1] recent DNA research confirmed that the likely source population for all invasive S. invicta in the United States occurred at or near Formosa, Argentina, and virtually ...
A vial filled with fire ants (Solenopsis geminata), a species identified as a human health hazard. Tramp species can have similar effects to invasive species, and in some literature the term "tramp" species is used as a synonym for invasive. [14] [15] [6] [5] As such they can outcompete and displace local fauna, decreasing species richness.
