Camponotus punctulatus is a carpenter ant from Argentina. They make massive mounds in open pastures.

This might sound very pedestrian and boring but it's very odd that a carpenter ant is building mound.

Solonopsis (fire ants) make small mounds and are a real hazard because they sting. Camponotus punctulatus can't sting. Yet these carpenter ants change the landscape.

Very little documentation on these ants. Morphologically they look very similar to other carpenter ants.
