Re: How do I know when I'm faced with guard bees?
You'll see badges on them.
What are you asking? I don't think I understand what you are searching for. "Gaurd bee", by definition, gaurd the entrance of the hive. So, they would be found there. That doesn't mean that bees found other places in a hive won't act defensively. All of them, except the drones, can sting. Some are more prone to. But, you can't tell by looking at them. They'll tell you by their actions.
