When giant ‘murder’ hornets attack, honeybees scream to alert danger, study says

To guard their hives from such a disaster, some species of honeybees have developed an arsenal of defensive strategies. They might forage for different animals’ feces and place it at their nest’s entrance to repel predators, a tactic known as “fecal recognizing.” Or, in a way often known as “balling,” a cluster of honeybees could engulf a hornet, vibrate their flight muscle groups and produce sufficient warmth to kill the enemy.
