The online resource for Megalomyrmex related research!
The genus Megalomyrmex (Formicidae: Myrmicinae: Solenopsidini) comprises 44 described species. At least ten Megalomyrmex species are thought to be associated with fungus-growing ant hosts consuming fungus garden and host brood and all others are free-living predators. Within the silvestrii species group, there is a gradation of parasitic behavior that includes lestobiotic parasitism, also described as raiding "thief ants" (e.g., M. mondabora, M. mondaboroides and M. silvestrii), agro-predatory associations, where the parasite usurps the nest and fungus garden (e.g., M. wettereri), and the cohabiting "guest ants" or xenobiotic parasitism (e.g., M. wettereri, M. symmetochus, and M. adamsae).
About Rachelle M. M. Adams
I explore trait evolution at ecological and evolutionary time scales in arthropods. My interests are in how symbioses evolve and shape ecosystem diversity focusing on species interactions and co-evolution of symbiotic networks. I study the Megalomyrmex parasite-host ant system that I developed but am interested in all arthropod symbioses.
Please see Research Projects for a selection of projects I am working on!
