Natural History

This species is mainly known from Winkler samples of sifted litter from the forest floor. It is relatively common in Winkler samples from lowland and mid-elevation wet forest habitats. It is less often collected using other methods. Nichole Barger made one collection of urichi while baiting at La Selva Biological Station. Bill Eberhard observed a flight of males from a nest in the ground near his home in Cerros de Escazu. Nevermann found the type series of nevermanni (now a junior synonym of urichi) in a rotten log, in company with Pachycondyla stigma.
