The Lasius umbratus, known as the Yellow Shadow Ant, is a fascinating “hidden” species of the temperate world. These ants spend almost their entire lives underground, tending to root aphids for honeydew. They are prized by keepers for their stunning bright yellow to orange color and their status as a temporary social parasite. They don’t just “build” a colony, they “conquer” one.
