Wasps that are five times larger than honey bees are natural enemies of honey bees. While honey bees can sting only once and die after attacking, a single wasp is capable of stinging multiple times and is highly venomous. What is more, a wasp can kill hundreds of honey bees with its big and strong jaw. Once wasps raid a hive, they kill the bees and plunder larvae and honey. They are just like devastators.
However, honey bees do not retreat easily. When a scout wasp appears to find out a hive, the bees inside go out to call in other bees collecting honey outside. If more wasps attack them, honey bees desperately fight against them to keep their beehive. A group of bees quickly surround the invading wasp just like a ball, and vibrate their wing muscles to generate temperatures of about 46℃ [114.8 ℉], which is hot enough to kill the wasp. Apart from the temperature, they even increase carbon dioxide concentration suddenly to kill it.
The number of honey bees that are sacrificed in the process is not small, but they unite to protect their home.
