Yes, they will do just about anything. Without the queen the colony will disperse and die. If they try to join another colony they will be attacked and killed.
I've never heard of that either. I do know that in the spring carpenter ants and termites exhibit a behavior known as swarming. They have wings and leave the main colony to establish a new one, then die off. That is their only purpose. When I worked in pest control I saw sides of houses and buildings covered with them. Maybe bees do the same thing.
