Yes Myrimica rubra do have lots more queens in the nest.. I have a colony myself with around 8 queens. Lasius niger on the other hand only do have ONE queen, any more and the workers will fight untill there is only one left.. and sometimes even both will die.. so its not even almost worth the risk.
Hello, Yes as everyone said Lasius niger colony has only one queen, but productivity is fast enough, well if u want to have a lot of queens u should try Myrmica rubra.. or find out more ant species which have more when one queen.
I've tried this myself, its ok when there are a small number of workers as they can't take on a queen, but when there are alot of them, say about 20 they will some how kill the other queen and yes sometimes you are even left with no queens at all.
