Natural History:

This is a relatively common species in Costa Rica, as revealed by its frequent presence in samples of sifted leaf litter from the forest floor (Winkler samples). However, I have rarely seen nests. I once observed a nest under a stone in the moist forest/dry forest ecotone at Maritza station in the Guanacaste Conservation Area. I once observed a dealate queen that fell out of a Cephaelis stem I was dissecting in Braulio Carrillo National Park.
