Argentine ant

The Argentine ant is a small, brown ant species native to South America. They are known for their aggressive behavior and ability to form large colonies, often displacing other ant species. These ants thrive in warm environments and have spread worldwide, including parts of the United States, Europe, and Australia. Argentine ants are notable for their lack of territoriality, meaning that colonies can merge, creating supercolonies. While they play a role in their ecosystems, they can become pests when they invade homes and gardens, competing with native species and disrupting local ecosystems.
