Ectatomma tuberculatum

photograph © Alex Wild 2007

Visitors to the rainforests of central and south America looking for ants will undoubtedly see Ectatomma.  These large ants are abundant in the forest understory.  Here, workers of Ectatomma tuberculatum guard extrafloral nectaries of an Inga sapling in a Panamanian forest.  They carry nectar in their open jaws, and the ant in the foreground shows a droplet on her left mandible.
