I am afriaid of bees and/or hornets (and am man enough to admit that) but I cannot deny how cool they look. These japanese hornets are quite possibly the most deadly insects on the planet. lets lay down some facts: The worlds largest hornet at 2 inches with a three inch wingspan. The stinger is a quarter inch long. Its venom is a deally concoction of eight different chemicals and has the ability to bore a hole through human skin. Can fly at speeds of 25 miles per hour. Kills full grown Yaks. Most deadly, venomous killer in all of japan. Eats bumble bees. BADASS.
