The Lasius brevicornis, commonly known as the Short-horned Yellow Ant, is a hidden gem of the North American landscape. Much like its cousin L. flavus in Europe, this species is a subterranean specialist. They are beautiful, shy, and possess a stunning golden-yellow to orange coloration. Because they spend the vast majority of their lives underground tending to “root aphids,” they have smaller eyes and a much more peaceful temperament than their surface-dwelling relatives.
