Natural History

I know this species from four collections, all from mature forest sites on the slopes of Volcan Barva. At the 500m site on the Barva transect I collected a worker in the canopy of a Licania tree, about 20m high. I also found workers at 950m on the Barva Transect and at the old Carrillo station near the bridge over the Rio Sucio. These workers were among general collections from all habitats. Jim Wetterer collected the species at Rara Avis.
