I recently captured 3 ant queens. Two Myrimica Rubra and one Lasius Niger. I was wondering if anyone could help me by giving me any hints or tricks to give my colonies the best chance. I have had the colonies for about 2 weeks and I have seen the Lasius Niger queen on the surface. I have placed stones in the nest so it is not always visible. Is this natural behavior? Or has the queen decided nowhere is suitable and decided to keep looking. Again I am not sure if it has dug a burrow or not. I cannot see any eggs but this may just be because of obscured vision. Any help would be welcome.
