TWO CHARGE SOURCES. “Bees are not electrically connected to the earth, like flowers are, yet they also gain a charge as they fly through the air. The acquisition and maintenance of charge on a bee is a key factor in their ability to detect electric fields, with just slight increases in charge causing large gains in electromechanical sensitivity of both hairs and antennae.”
