That works with a lid on, but how will you feed them without removing the lid?
I am pretty sure that they will not be always on the lid, plus you can just dump some that have escaped back in
Currently keeping:
1x Formica subsericea, (used to be polygynous) 15+ workers with 4 pupa (Idk why they still have)
1x Lasius umbratus, (Workers accepted) 5+ workers with host brood
1x Ponera pennsylvanica, just queen
As you watch your ants march, remember: every journey begins with a single step (or queen)-not just towards you, but towards a future woven by diligence and shared dreams - Me
