Three common English phrases refer to bees:
You can be "a busy bee", because we all know bees are hard workers.
If something is "the bee's knees", it's great. I don't know why, I would have to look it up.
And if you have something on your mind that you won't shut up about, then obvisouly you "have a bee in your bonnet", even though no one wears bonnets anymore, except during historical reenactments.
My question is this - what are the common bee-related phrases in other languages?
