Natural History

I know this species from relatively few collections. They have all been from very weedy open areas. The species seems to have small colonies in very ephemeral nest sites. At Sirena in Corcovado National Park I found workers while collecting at night in an old guava plantation. Another time I was collecting in an area of open Sida and grasses, and down in the leaf litter I found an aggregation of workers, some brood, and a queen. Several minor workers were dragging the queen to and fro. There was no nest structure. At La Selva Biological Station the species is only known from around the lab clearing and administration area. Ronald Vargas found a nest in a rolled Heliconia leaf. Alate queens have been taken at the lab clearing blacklight (3 March 1989).
