Good question! I don't know for sure (my sources aren't specific, and I'm not an expert on bees), but I have a hunch that they simply starve to death. I know that in honeybee hives, the males are quite useles when it comes to taking care of themselves - they basically mooch off the workers. Any males left in the hive when a queen leaves are driven out, and they simply don't have the survival skills to last long. So, probably those that mate with a queen face the same problem - the hive won't let them back in, and they starve. This situation is fine with the queen, since she can store enough sperm from a male to last the rest of her life. In another social species, termites, the queen doesn't store sperm in the same way, and so her king stays in the colony, to remate from time to time. Even in this case, he doesn't fend for himself, but is completely taken care of by the workers - just as the queen herself is.
