Specimen Labels

At Cuzco Amazonico, near Puerto Maldonado, Madre de Dios, Peru, Stefan Cover and John Tobin found a population of capillata colonies in a grassy clearing on the Madre de Dios River. The nests were in heavy clay, and the workers were observed foraging on cloudy days and at dawn and dusk. The species was absent from the adjacent rainforest. (Wilson 2003)
