Healthy planet, anyone?
It’s years since I visited Oakland’s Museum of California – now known as MOCO – and learned that bees sang for their supper. Put another way, bees, upon alighting on a plant – sing an appropriate song to induce the plant to release its nectar and feed the bee.Now, I learn that bees scream when attacked by murder hornets A recent study:
… published in the Royal Society Open Science journal… revealed that bees release a “rallying call for collective defence” against the hornets. The previously undiscovered signal, now known as an “anti-predator pipe, shares acoustic traits with alarm shrieks, fear screams and panic calls of primates, birds and meerkats”…. Will humans learn the even a fraction of what makes our wonderful planet tick before we destroy all of nature?
Bees produce the sound by vibrating their wings or thorax, elevating their abdomens and exposing a gland to release a pheromone.
