Natural History
This species occurs in wet forest habitats. It occurs in a low proportion of Winkler samples of sifted leaf litter from the forest floor. I have collected it several times as foragers on the ground or in low vegetation. At La Selva Biological Station, I found a nest in a dead stick near a stream edge.
