Apterostigma (genus)

Apterostigma is a genus of ants found primarily in Central and South America. They are characterized by their small size, specialized nesting behaviors, and often subterranean lifestyles. Unlike many ants that have wings or visible queens and workers, some Apterostigma species lack wings entirely. They are notable for their mutualistic relationship with certain fungi, which they cultivate as their primary food source. These ants play a role in soil aeration and nutrient cycling, contributing to their ecosystems. Their unique behaviors and adaptations make them an interesting subject of study for understanding ant diversity and symbiotic relationships.
