I've seen the documentary that was a part of on the Discovery Channel I think. I couldn't believe it even after seeing it. I don't know why the dumb honey bees just don't jump 'em together. Dumb honey bees. Let them try to do that to a colony of African killer bees...
FYI : if you guys thought that video was incredible, you should see what Japanese honey bees do to kill wasps/hornets. This was in that same documentary. The Japanese honey bees stand tall and deliver a knockout punch for honeybee-kind. I just remembered this was also in that documentary. http://www.bio.davidson.edu/people/midorcas/animalphysiology/websites/2001/Thawley/defense.htm Now that's bad-ass - they give them heatstroke and fry them.
This is pretty stale, but topical. http://news.nationalgeographic.com/news/2002/10/1025_021025_GiantHornets.html
