Bees don't just leave their queen and fly off. If there's a queen there's brood but if the queen dies the workers begin to disperse, and also start to lay (haploid) eggs that only hatch into drones which also disperse. On the other hand, colonies will migrate if their environmental conditions are not ideal. It's a phenomenon called "swarming" and it happens all the time even with domestic livestock.
