Biology Longino (1997): "This species occurs in mature wet forest. It is a relatively common arboreal ant, nesting in dead branches and under epiphytes. Colonies often appear large, with workers scattered over a wide area." Males are present in Wheeler's type series, collected on 16 May in an epiphyte (Tillandsiarum streptophylla).
