This species is relatively common in Monteverde; I have made collections from four nests, and have seen several other nests from which I did not make collections. The colonies are small, and nests are always underground, either with an entrance that is a simple hole at the surface, or emerging into chambers beneath a stone or dead wood. For example, I once turned a dead log and observed workers grab brood and vanish down a tunnel. The tunnel extended down about 10cm to a bottom chamber, where I found only 5 adults, 1 pupa, and 3 larvae. Isopods appear to be the main component of the diet, because the nests are usually surrounded by refuse piles of bleached isopod shells. I have discovered nests in road banks because there was a telltale whitish-gray streak of isopod shells that poured down the slope from the nest entrance. I once excavated a colony and kept it alive for several weeks, offering it a variety of prey. Foragers would take only isopods. Counter to this observation, however, was a worker I captured running across the road carrying a spider as prey.
