This species inhabits wet to moist climate areas, in mature forest or second growth vegetation. In lowland sites it can occur in both mature and second growth forest, but at higher elevations is increasingly restricted to open or disturbed habitats. Workers are diurnal. The species is relatively common in canopy fogging samples at La Selva Biological Station.
Nests are in narrow-guage dead stems. Most nests I have encountered have been in stems 4-10mm outside diameter. Nests can be populous: a nest I found in a dead Cecropia petiole lodged in low vegetation contained 319 workers. Nests commonly occur in low vegetation, so the species is frequently encountered and collected.
