Natural History:

This species inhabits the forest floor leaf litter in mature wet forest habitats. I know it from 9 Winkler samples of sifted leaf litter, and a collection from a very rotten but still vertical treetrunk. Dana Meyer, a student working at Sirena in Corcovado National Park, collected a live colony from under a rotten log and observed it for a period of time. His notes indicated that the colony (1) took small isopods but not small flies; (2) was possibly polygynous; and (3) had lighter-colored ergatoid queens.
