Natural History:

This species prefers open, sunny habitats, including the high canopy of rainforest, secondgrowth vegetation, and isolated trees in pastures and around dwellings. It is a relatively common species, and conspicuous due to its color pattern. I most often encounter it on treetrunks and in treefalls. In spite of its commonness, I have only seen nests once. I was collecting in a canopy Ficus, and I found many nests in live branches. The nests were in the very tips of the branches, with inside diameters 5-8mm, outside diameters 15-20mm. The nest chambers were irregular, as though excavated by the ants and not preformed by the plant. Workers were very abundant in the crown of the tree, suggesting a large, polydomous colony with nests in many branches.
