A worldwide community photographing and learning about wildlife
Lasius Flavus
I'd guess they're red ants, but they're really far more brown/yellow/orange than red. Small nest under a plant pot, no more than 20 ants outside the nest
Ants are really fascinating animals, but they've been around a very long time and have undergone a lot of evolution and speciation. They have also been widely spread from their native habitat to others. As a result, it may be difficult to ID these to the genus level.
