I spotted Lasius Flavus (yellow meadow ant) nest from the grass (7/2008), when I was cutting it. Sand is somewhere, where it should not be is a sure sign. And when I took a closer look, I was happily surprised, that it was not a Lasius Niger nest but there were small beautiful yellow ants running around. I cannot remember, when I last time saw Lasius Flavus, and now there is a nest at my backyard. Now I'm going to follow the progress of the colony and you can read about it at my backyard ant map. Lasius Flavus Lasius Flavus (Yellow Meaadow ant) is common in Central-Europe. Lasius Flavus is, as the name says, yellow. The queen is 7–9 mm long and workers 2–4 mm. Their color varies from yellow to brown, with queen and males being slightly more darkly colored. The Yellow Meadow Ant feeds on the honeydew from root aphids and small insects. In the beginning, colonies are often founded by multiple queens. Later on, fights between the founder queens will erupt, with only one queen left (monogyny). 
Picture 1. You cannot spot the nest very far. 
Picture 2. Some unexpected sand in the grass gives you a hint, that there might be an ant nest close. 
Picture 3. Several beautiful yellow ant. 
Picture 4. Three ants. 
Picture 5. I should have a better camera...
