Distribution
This species ranges from Guatemala to Colombia, and can also be found in Costa Rica.Reproduction
"Atta colombica" produces visible refuse dumps of spent fungus on the surface. These dumps often take the form of large, conical mounds, and are located to the side of the main soil mounds. Lines of workers carry the spent fungus from the nest to the dumps. They deposit the grayish-white pellets at the peak of the mounds, which produces the conical shape. This behaviour is different from "A. cephalotes" which deposit their refuse in subterranean dumps.References:
