I have an ant question!
I have an ant farm with Little Black ants but not a queen. can one of the ants become a queen?
I'm afraid once an ant becomes an adult ant, it can no longer change form or shape. It can't shed its skin or grow.
Adult worker black ants can not become queens, and the worker ants can not lay eggs that will become queens either.
There are a few types of ants where special workers become "queens," but those ants are much more like wasps, and you wouldn't want to keep them in a regular ant farm. If you'd like a more detailed explanation, check the ant queen development post.
How are your little black ants doing? I hope they are doing well.
