Great @adalger, another phase of the project accomplished, I hope the ants decide to move in completely. Also, the size difference between the queen and the first workers is really remarkable, here generally the first worker ants that are born are called "nurses", I don't know if in Europe they are called the same Hehe. On the other hand, I don't know if this species has different castes among its members, like soldiers or collectors to mention a few, where the morphological differences are very noticeable, I will be attentive to the next episode where you will talk about their characteristics.
