Natural History:

Pachycondyla stigma is well-known as a tramp species found throughout the world in the tropics. It is very widespread, and is able to colonize remote oceanic islands. It is extremely generalized with respect to nesting sites and habitats. I have collected it in mangrove swamps, banana plantations, and mature rainforest. It usually nests in dead wood or under loose bark. Nests may occur at ground level, in the low arboreal zone, or in the canopy. Colonies are small and inconspicuous.

This nest observation is from Corcovado National Park: In canopy of tall Licania (Chrysobalanaceae) tree. Nesting in rotten wood protruding from a knothole. The material was humus-like, covered with moss. The nest was in the form of small, inter-connected chambers, each about the size and shape of half a peanut shell, containing 5-10 larvae of varying sizes, some with 3-4 pupae.
