biology Longino (1997) found two colonies in primary rainforest on the Costa Rican Atlantic slope, one nesting in a rotting cavity of a live branch, the other in a dead stick. Douglas Yu (specimen data) discovered a colony in Peru in cavities of the myrmecophyte Cordia nodosa. Colonies have been found in rainforest nesting in dead sticks and in the cavities of live myrmecophytes of the genera Cordia and Piper. Winged reproductives have been collected in nests in different localities from April to November.
