Biology
Megalomyrmex adamsae is a specialized social parasite of Attini, like its close relative M. symmetochus. Colonies cohabit nests with their attine hosts as "guest ants," feeding on fungal mycelia and attine brood. Megalomyrmex adamsae and M. symmetochus differ in host preference: M. adamsae is typically found in Trachymyrmex nests, M. symmetochus in Sericomyrmex nests.
