The Pheidole megacephala, famously known as the African Big-headed Ant, is one of the most successful and aggressive invasive species on the planet. For an ant keeper, they are the “Formula 1” of colonies: they grow at light speed, eat everything in sight, and feature a dramatic caste system with tiny workers and massive, heart-headed soldiers. While they are fascinating to watch, they are notorious escape artists and require a keeper who can stay ahead of their explosive population growth.
