Natural History:

This species is one of the most common in lowland Costa Rica. It is very abundant in the Pacific lowlands and the southern Atlantic lowlands (e.g. Hitoy Cerere Biological Reserve) but is relatively less abundant in the northern Atlantic lowlands (e.g. La Selva Biological Station and vicinity). It prefers low, scrubby vegetation and is rarely found in mature forest. Workers are diurnal. Nests are almost always in small dead stems that are in low vegetation or even on the ground in open areas. The exception was one nest I observed in a live internode of a Cecropia sapling at a pasture edge. The habitat preference of C. brevis is revealed at La Selva Biological Station, where it has been collected once by manual search at ground level in a disturbed area, and once in a Malaise trap, yet has not occurred in 52 canopy fogging samples.

In Corcovado, I observed a nest in a dead Cassia stem that was immediately adjacent to a large carton nest of an Azteca colony. Thus the species is not excluded by Azteca, and may even benefit by nesting near them. It would be worth investigating whether they share foraging trails with Azteca.
