Natural History:

This species is known from few collections. Earlier records are almost all from shipments of orchids intercepted at U.S. quarantine stations (Kempf 1958, Andrade and Baroni Urbani 1999). My own collections have all been from the Atlantic slope rainforest on the Cordillera Volcanica Central. The one nest collection I have made was from a recent treefall at La Selva Biological Station. It was from a part of the treefall with a big branch of Stryphnodendron excelsum, some smaller Pentaclethra macroloba branches, and a tangled mass of Norantea sessilis. There were two Cephalotes nests in different parts of a live Norantea stem. One stem was 12mm and the other 15mm in diameter. In the field I thought they were part of one polydomous colony, because they were in such close proximity, but I later discovered that one nest was C. curvistriatus and the other was C. maculatus.

Other than this nest collection, I have seen workers from three other canopy samples from La Selva, and two canopy samples from a 500m elevation site in Braulio Carrillo National Park above La Selva.
