Synonyms

In Chile Solenopsis gayi can be found living in mixed nests with the ant Camponotus morosus. Believed to be a parabiotic association, the relationship between these two ants was studied and it was found S. gayi workers were tolerant of all C. morosus workers. C. morosus workers were aggressive to most other ants except their own nestmates and the S. gayi workers they lived with. (Errard et al. 2003)
