Honeybees found using tools to repel giant hornets

Postby oneh2obabe » Dec 9th, 2020, 2:02 pm

Nature keeps evolving to defend itself against predators.
In East Asia, honeybees must contend with never-ending attacks by a formidable foe: giant hornets. These predators pick off individual bees, but also stage group invasions of hives. In a brutal onslaught, these large wasps first decapitate every bee they encounter, then occupy the hive and take their time devouring the bees’ larvae.

To defend themselves against hornets, Asian honeybees have evolved various creative tactics, such as swarming invaders with hot “bee balls,” roasting them to death.

But in new research from Vietnam, scientists have discovered an even stranger bee trick: Coating the hive entrance in animal dung.

This “fecal spotting” not only repels giant hornets—it’s the first clear example of tool use in honeybees, says Heather Mattila, anentomologist at Wellesley College in Massachusetts and co-author of the study, published December 9 in the journal PLOS ONE.

Dance as if no one's watching, sing as if no one's listening, and live everyday as if it were your last.

Life is not about waiting for the storm to pass. It's about learning to dance in the rain.
