How do you plan on keeping a Polyergus colony? Yes, there is proof that some people do it, but that doesn't make it a good idea.
The process is likely more akin to how Lasius parasites found colonies. I wouldn't think Polyergus queens retained the same instincts as Formica or are even physically capable of opening cocoons.

If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.
Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.
