Ant Living in a Fanged Pitcher Plant

Description

These ants are immune to the pitcher plant’s digestive liquid—they drag a grasshopper out to eat, simultaneously helping the plant by removing the large insect that would spoil in the liquid. The ants live only on this pitcher plant, raising their young in its hollow tendrils. They can walk across the slippery rim and swim and dive in the fluid, and they also hunt the mosquito larvae that breed there and would otherwise take the plant's nutrients.
