I have a healthy hive with yellow honey bees, but recently I saw lots of black bees at the entrance and it seemed like they were fighting with my yellow bees. Could it be that the queen had mated with a black drone and finally the queen produced his genes? Or some hungry hive is trying to rob this hive? http://picasaweb.google.com/Luckyparrot2009/Blackbee#

That looks more like a hornet from the pic, really hard to tell.
A good close up of the wings showing the pattern would be helpful.

G3, I lost my closeup lense, so I'm using the regular lense(17-55mm), and that's as close as it can be. Assuming it a hornet, should I be concern? What are they she doing inside the hive ? I saw lots of them flying in and out of the box.
Michael, eventhough I'm not sure it's being robbed or not, I reduced the entrance anyway.
