The mechanism by which palatable species take advantage of their similarity in appearance to those that are unpalatable, in order to avoid predation, is called Batesian mimicry. Several arthropods are thought to be Batesian mimics of social insects; however, social insects that are Batesian mimics among themselves are rare. In Malaysia we found a possible Batesian mimic in an arboreal ant species,Camponotussp., which was exclusively observed on foraging trails of the myrmicine antCrematogaster inflata. The bright yellow and black colouring pattern, as well as the walking behaviour, were very similar in both species. We observed general interactions between the two species, and tested their palatability and the significance of the remarkably similar visual colour patterns for predator avoidance. Prey offered toC. inflatawas also eaten byCamponotusworkers in spite of their being attacked byC. inflata, indicating thatCamponotussp. is a commensal ofC. inflata. An experiment with chicks as potential predators suggests thatCamponotussp. is palatable whereasC. inflatais unpalatable. After tastingC. inflata, the chicks no longer attackedCamponotussp., indicating thatCamponotussp. is a Batesian mimic ofCrematogaster inflata.
