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) 20+ workers
1x Lasius umbratus, (Workers accepted) 25 workers with host brood (I think they are dead now lol)
1x Crematogaster cerasi 4 workers with brood (still growing)
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
