This species is one of the most common in the low arboreal stratum in primary wet forest at La Selva. Workers make prodigious use of loose carton, constructing extensive runways and shelters. Nests are often built in and around dead sticks, dead vine stems, palm bracts, and bark flaps. Nests are common on tree trunks among epiphyte roots. Epiphytes frequently sprout from the carton, in some instances producing discrete ant gardens. Opportunistic nesting in myrmecophytes (e.g. Cecropia, Tillandsia bulbosa) may occur (images of nest in T. bulbosa). Somewhat disheveled galleries and brood-containing carton shelters may occur abundantly in the understory, making it difficult to determine colony boundaries. The general nesting habits of this species are much like Crematogaster longispina.
In one case at La Selva, ant gardens were scattered in a Piper reachable from the bridge over the Sura, at the entrance to the arboretum. The ant gardens looked ephemeral (one was on the tip of a dead branch), and carton galleries traversed the branches. The sprouting epiphytes were mostly small aroids.
