Its a fictional universe. The bees could be a different species than any found in the real world that are a lot more aggressive, and with a more painful sting. Maybe their sting is like that of bullet ants.
The bullet ants btw supposedly have the most painful insect bite in the world. They reduce the guy in that vid to a puddle of tears.
Ah those things, they're evil and they do have the most powerful insect bite in the world basically the equivalent of being shot which continues non stop for a day or something like that.
There is a type of flying insect called the tarantula hawke, it's a wasp with the second most powerful bite in the world that is unbearable you and the only thing you can do is scream though it's short term about 3 minutes.
Getting stung by either of them would suck, I imagine that it would be closer to hawk wasp just more ferocious which is something I agree with you with, who knows what kinda bees these are and how powerful they are, I don't think they're to happy with being trapped in a jar then thrown at someone or something.
