Fire ant queens. Even if only one queen survives, within a month or so, the colony can expand to thousands of individuals. Some colonies may be polygynous (having multiple queens per nest). Fire ants are resilient and can survive floods. During Hurricane Harvey in Texas in 2017, clumps of fire ants, known as rafts, were seen clumped together on the surface of the water. Each clump had as many as 100,000 individual ants, which formed a temporary structure until finding a new permanent home. Fire ant queens, the reproductive females in their colony, also are generally the largest. Their primary function is
Red imported fire ant the funiculus in workers and queens, and the second and third segments of the funiculus are twice as long and broad in larger workers. Polymorphism occurs in all species and the mandibles bear four teeth. The following cladogram shows the position of the red imported fire ant among other members of the "S. saevissima" species-group: Phenotypic and genetic data suggest that the red imported fire ant and the black imported fire ant ("Solenopsis richteri") differ from each other, but they do share a close genetic relationship. Hybridisation between the two ants occurs in areas where they make contact, with the
