Wasps

 

As explained in the video above.  Wasps look very different from bees.  There are many all over the world such as yellow jackets, hornets, wasps, carpenter bees, dung beetles.  Basically anything that flies and buzzes people mistake for some sort of bee.  Check out the picture of a wasp.  Or click this word bee to see a bee.  Basically I do a good job of explaining the difference above in the video.  You can also go to this page to see more videos of bees and what they look like.
