When I was playing around with the bees in the snapshot I heard that if you hit one it will act like a wolf and come for you in a big group. But when I switched to survival to try it they wouldn't sting me, they would chase me, and try to sting me but nothing that caused harm, I stood in the middle of all the bees and tried it again and stood there for a while.. still nothing, they never even took a heart from me. Now, I don't know if this is a bug but I'm sure it shouldn't be happening...
