Carpenter Bee

This is a male Eastern Carpenter Bee, Xylocopa virginica.  It is easy to tell the difference between males and females, as long as you can see their heads.  Males have a white or light yellow face, whereas females have solid black faces.  There is also a difference in shape of the compound eyes.  Carpenter bees in general are normally docile, but males do not even have a stinger, so there is no worry of them harming you at all.

This one is crawling on my hand, in case you were wondering.
