Bees emit alarm sounds similar to mammals during hornet attacks.

During research in Vietnam, scientists recorded alarming sounds made by honeybees when giant hornets attacked their hives. This study, published in Royal Society Open Science, marks the first documentation of these sounds, highlighting how honeybees react to threats from the world's largest wasps, often misnamed "murder hornets" in the U.S. The phenomenon, known as "antipredator pipes," consists of harsh calls distinct from the usual buzzing of honeybees, serving as a distress signal.
