never mind, I googled it. INteresting. America did not have any before they were imported. And yet, they are vital to america today. One case where the introduction of a foreign species has been very benign.
No honeybees, but in Mexico and Brazil there were stingless bees...and bumblebees seemed to have ruled well enough over the U.S. and Canada...as well as those annoying sweat bees.
Of course the introduction of honeybees has affected the native species a bit, they don't seem to be in danger. In fact, bumblebees have an interesting technique where they vibrate and warm themselves up to forage early in the morning before honeybees become active.

*sigh* I really gotta stop learning.
