Colobopsis is a genus of ants commonly known as "turtle ants" due to their unique defensive behavior. These insects have a distinct flattened head and a tough, turtle-like exoskeleton that provides protection against predators. They are known for their powerful mandibles, which they use to defend their colonies by biting and spraying formic acid. Colobopsis ants are primarily found in tropical regions and play important roles in the ecosystem as decomposers and seed dispersers.
