Harvester Ant

Arid and semi-arid environments, grasslands, and deserts throughout North and South America; they typically nest in the soil with large mounds.

Primarily granivores that collect and eat seeds, though they occasionally scavenge for dead insects.

They are known for clearing large circular areas around their nest entrances. They exhibit distinct worker castes and use pheromone trails to coordinate communal seed gathering.

Benefits: Major seed dispersers and soil aerators. Risks: Possess a potent sting that can cause severe pain and allergic reactions in humans; they are generally more aggressive when protecting their nest.
