I have seen this before on the Discovery Channel. Those hornets are moving north from South America and Mexico. The Honey Bee's in that region do have a defense for them. It starts not with the invasion and fighting the invasion, but with the scout that the hornets send out. Before a hornet invasion can happen, they have to mark the nest they are going to invade. That is what the hornet scout does, he marks the nest with a scent. The honey bees in that region jump the scout. They don't kill it by fighting it though.....they kill it in a unusal way. 50-100 of the honey bees jump on the hornet and kill it by raising his body tempature to a level that he dies. If I remember, the hornet can withstand up to 107.5*.....and the honey bees raise his temp to around 108*. So, with the scout dead, the invasion never happens. Wierd how nature works sometimes.
