The Lasius emarginatus, also known as the “European Rock Ant” or the “ManhattAnt,” is often called the “Red thorax Lasius.” While its cousin Lasius niger is the standard black garden ant, L. emarginatus is the more colorful, faster, and more adventurous relative. It is famous for its incredible adaptability, recently gaining worldwide fame for invading New York City skyscrapers. If you want a beginner friendly ant that is slightly more “high octane” and visually striking than the common garden ant, this is the perfect choice.
