"When bees fly through the air outside the hive, they collide with charged particles, from dust to small molecules. These impacts tear electrons away from their cuticle—their outer shell—and the bee ends up with a positive charge. When they return to the hive and walk or dance about, they give off electric fields. And Uwe Greggers from the Free University of Berlin has shown that they can detect these fields with the tips of their antennae. Despite our long history with the honeybee, there could still be a secret world of electric communication within the hive that we know nothing about."
