Media BGR reported that some parts of the United States recently encountered a terrible “killing bee” invasion, the attack on the killer bee may be painful, but this giant Asian bumblebee is more of a threat to the local bee population than the threat to humans. Japanese bees can effectively “cook” bumblebees alive by flapping the heat generated by their wings, according to a study.
The study notes that the real danger posed by “killing bees” is not to humans, but to local bee populations, which are quickly wiped out by “killing bees”. Dozens of “killing bees” have the ability to wipe out tens of thousands of bees in a short period of time. It’s worth noting, however, that Japanese bees have “come up with” an incredible tactic to ward off killer bees.
When a killer bee breaks into a hive, it is much larger than any other bee. However, Japan’s bees have used their numbers to their strategic advantage. Specifically, The Japanese bees pounce on the attacking mastobees and surround them completely. At the same time, bees start flapping their wings as fast as they can to generate heat, eventually “cooking to death” by effectively killing bumblebees.
According to a previous study published in LiveScience:
Bee bee stings can’t penetrate the thick skin of the bee, so the bee instead surrounds the attacker, forming a spherical ‘bee ball’ and uses its vibrating flying muscles to generate heat. The quality of these bees will cause temperatures in the area to reach 116 degrees Fahrenheit (about 47 degrees Celsius), enough to kill bumblebees.
Scientists discovered these bee spheres in 2005 and have been studying them ever since. Now, researchers have figured out the mechanism seces that regulate the behavior of Japanese bee-hot “bee balls”, but their close relatives, European bees, do not.
