Giant Hornets vs BeesJapanese giant hornets attack any bee colonies they find. European honey bees are defenseless against them. They have thick armor that honey bees can't penetrate with their stingers.
As few as 20 giant hornets can kill 25,000 honey bees in a few hours. This makes it very difficult to raise European honey bees in Japan.
Japanese honey bees have a defense against the giant hornet. They attack as a group and surround the hornet. They beat their wings vigorously to generate heat — creating a ball of heat (46 °C, 115 °F) that the giant hornet can't survive.
Giant hornets attack any insect they find. Most insects have no defense.
Giant Hornets vs HumansGiant hornets aren't aggressive unless they feel threatened. Their venom is no more poisonous than a regular hornet or bee. However, they inject far more venom per sting.
Each year, they claim around 40 lives in Japan (anaphylactic shock). That's more than any other animal in Japan (poisonous snakes claim 10 lives each year).
Giant hornet stings are painful and require hospital treatment. The pain of a single sting has been compared to being shot with a nail gun. As with regular hornets, they often attack as a group.
Revenge of the HumansFried giant hornets are considered a delicacy in several remote Japanese mountain communities.
