Cindi, you are talking about a National Geographic Wild Chronicles documentary on Japanese Hornets Bees.
"A small but highly efficient killing machine lurks in the mountains of Japan â€”the Japanese giant hornet. The voracious predator pumps out a dose of venom with an enzyme so strong it can dissolve human tissue. Just a handful of these hornets can kill 30,000 European honeybees within hours. Watch an attack of giant hornets on a beehive."
However, the Japanese honeybee has adapted and survives these giant hronets!
I have the documentary on ZuniBee.com. You can watch it at:http://www.zunibee.com/viewVideo.php?video_id=19&title=National_Geographic_Japanese_Hornets_Bees
