Giant hornets are apparently popping up in the news lately…
Hearing “giant” and “hornet” right after another, one should be scared. This is the case for western honey bees (Apis mellifera), who are no match for the Japanese Giant Hornet (Vespa mandarinia japonica). A group of 30 hornets can destroy an entire hive of 30,000 bees in about three hours. However, the Japanese honey bee (Apis cerana japonica) has a unique defense mechanism against this predator four times its size. When the hornet reaches their nest, 500 bees gather together and form a complete ball around the hornet, making it immobile. The bees then start to vibrate their flight muscles so quickly that they raise the temperature inside the ball, acting like a convection oven and essentially baking the hornet to death within an hour.
