Identification
Generally similar to S. invicta in color and morphology. Differentiation is based on the lack of median tooth on the clypeus.

Due to variation within colonies, several major workers should be examined in order to ensure that this feature is absent.
Range
Historically the most common native fire ant across southern US(1), this species has been significantly reduced by the expansion of S. invicta.
Habitat
Mounds are not as large as S. invicta, often not seen at all.
