Distribution:


Neotropical Region: Alajuela, Cartago, Chiapas, Chontales, Comayagua, Costa Rica, Ecuador, Guanacaste, Guatemala, Heredia, Honduras, Jinotega, Limón, Matagalpa, Napo, Nicaragua, Peru, Puntarenas

Distribution Notes:

Peru (type locality), Costa Rica. Costa Rica: common in mid to upper elevation wet forest in Cordillera Volcanica Central northward through Cordillera de Tilaran and Cordillera de Guanacaste; also known from Cerro Rincon on the Osa Peninsula, but so far not collected from Cordillera de Talamanca; on Atlantic slope known to be a rare element of the fauna at La Selva Biological Station at 50m elevation, becoming much more common in Braulio Carrillo National Park, above 500m elevation.

Natural History:

This is a very common species in mid to upper elevation wet forests. I have collected it dozens of times as foragers on low vegetation and as an opportunistic cavity nester. I often find nests in dead branches, dead wood, and very frequently in chambers under epiphyte mats. The species can occur both in second growth vegetation and in the canopy of trees in primary forest. It seems to prefer well-insolated portions of the habitat, and is rare in the shaded understory. Unlike Camponotus JTL-016, I have never found this species nesting in live stems. For example, I have never found it in Cecropia internodes, in spite of extensive survey work. Nests are often small, usually no more than a few dozen workers, but colonies may be polydomous and thus it is difficult to say how large colonies can get.
