Fire ants are 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 color, though species of ants in many other genera are similarly named for similar reasons. Examples include Myrmica rubra and Pogonomyrmex barbatus.
The red imported fire ant, also known as the fire ant or 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 in 1916. Its current specific name invicta was given to the ant in 1972 as a separate species. However, the variant and species were the same ant, and the name was preserved due to its wide use. Though South American in origin, the red imported fire ant has been accidentally introduced in Australia, New Zealand, several Asian and Caribbean countries, and the United States. The red imported fire ant is polymorphic, as workers appear in different shapes and sizes. The ant's colours are red and somewhat yellowish with a brown or black gaster, but males are completely black. Red imported fire ants are dominant in altered areas and live in a wide variety of habitats. They can be found in rain forests, disturbed areas, deserts, grasslands, alongside roads and buildings, and in electrical equipment. Colonies form large mounds constructed from soil with no visible entrances because foraging tunnels are built and workers emerge far away from the nest.
Solenopsis fugax is a myrmicine ant of the genus Solenopsis.
Solenopsis is a scientific name for two genera:
The black imported fire ant, or simply BIFA, is a species of ant in the genus Solenopsis. It was long thought to either be a subspecies or color variation of Solenopsis invicta, but is now recognized as its own species with a demonstratively different range and living habits. BIFA seem to be more tolerant of cold and a less dominant species than RIFA.
Solenopsis daguerrei is a species of parasitic ants native to Argentina and Uruguay . The young queens of the species invade the nests of other species, such as the red imported fire ant (RIFA). This is made possible by the fact that the S. daguerrei queen produces pheromones which are very similar to those produced by the queens of the host species. The young queen finds a queen of the host species and latches onto it, eating the food intended for the host queen and slowly killing it. The S. daguerrei queen then begins laying eggs. These are taken care of by the host ants, sometimes preferentially to their own brood. S. daguerrei only produce winged virgin queens and males. No workers are needed, since these are provided by the host species. The winged ants fly off to mate and invade new colonies.
Megalomyrmex is a genus of ant in the subfamily Myrmicinae. The genus is known only from the Neotropics, where some of the species are specialized parasites or predators of Attini.
Solenopsis solenopsidis is a species of ant in the genus Solenopsis. It is endemic to Argentina.
Solenopsis molesta is the best known species of Solenopsisthief ants. These ants, which include the majority of species within the genus Solenopsis, 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.
