The Lasius neglectus, also known as the Invasive Garden Ant, is often described as the “super-colony” version of the common black ant. While they look almost identical to the standard Lasius niger, their behavior is worlds apart. They are a highly invasive, unicolonial species, meaning that instead of different colonies fighting each other, they form massive, interconnected networks where every ant is “family.” In the wild, they can dominate entire neighborhoods, but in a formicarium, they offer a high-speed, high-density experience for the keeper.
