Saw this on television:

Hornet scout goes out seeking honey;
finds honey;
returns to hornet scout friends.

30 hornets fly to nest with honey;
hornets bite off the heads of 30,000 honey bees;
every single bee is eradicated by 30 hornets;
hornets get drunk off of honey along with their little hornet layerlings (or those funny-looking eggs that the she-hornet lays).

2nd scenario:

Hornet scout finds honey nest of Japanese honeybee--dumb move;
Japanese honeybees surround scout hornet and madly beat their wings;
they beat their wings till it is exactly 117 degree Farenheit at which point the Scout hornet dies;
known only to Japanese honeybees till recently, one degree higher of wing beating (i.e., 118) and the honeybees would have died, but they're too smart for that.
