First Documented Case of Cleaner Ant Behavior Observed in Arizona Desert
Biologist Mark Moffett has documented the first known instance of cleaning symbiosis among ants, a behavior previously associated primarily with marine cleaner fish. In the Arizona desert, Moffett observed larger harvester ants (Pogonomyrmex barbatus) soliciting grooming services from smaller cone ants. The harvester ants would freeze and assume elevated postures, allowing the cone ants to scurry over their bodies, licking and nipping at their exoskeletons for periods ranging from 15 seconds to five minutes. This interaction, described in a paper published in Ecology and Evolution, suggests a mutually beneficial relationship. While harvester ants typically groom each other, the smaller cone ants may access hard-to-reach areas or remove detritus rich in fats from the harvester ants' seed-based diet. Alternatively, the exchange might facilitate the sharing of beneficial microbes, enhancing the microbiome health of both species. The sessions conclude when the harvester ants violently shake off the cleaners. This discovery highlights complex cooperative behaviors in insect societies, challenging the notion that ant interactions are solely characterized by warfare and slavery.
