Researchers have discovered that Florida carpenter ants perform sophisticated medical care on injured nestmates, including amputations. Ants can diagnose wounds, distinguishing between infected tibia injuries and femur injuries. For tibia wounds, they clean extensively, raising survival rates from 15% to 75%. For femur wounds, they amputate the leg after cleaning, boosting survival from 40% to 90%. The procedure involves licking, biting, removing the limb, and cleaning the new wound, taking about 40 minutes. This innate, cooperative behavior rivals human medical systems, showing ants’ remarkable ability to prevent lethal infections and enhance colony survival through complex, instinctive healthcare practices
