I found these ants on June 2, 2023 when they moved into a flowerpot in my workshop. They look a lot like the Tetramorium ants that I have, but they're much larger. They range up to 4-5 mm while my others are 3-4 mm long. Not only are they longer, these ants are much more robust and just generally bigger. Is there such a wide variation in the sizes of Tetramorium ants or are they something different? Thank you in advance for your answers to these questions.
