Japanese Honeybees Swarm Huge Hornet Predator To Kill It With Heat
Japanese honeybees face a formidable foe in the Asian giant hornet, a fierce predator that can reach 40mm long or larger, but the bees have developed a novel defense mechanism: they create a "hot defensive bee ball," swarming around the hornet and literally cooking it.
Now, a new study published Mar. 14 in the open access journal PLoS ONE uncovers some of the neural activity that underlies this unusual behavior, which is not practiced by the Japanese honeybee's European relative.
