By BeauHD from Slashdot's cause-and-effect department:
A new study published by the Entomological Society of America found that bees stop flying when the moon obstructs the sun during a total solar eclipse. "Using tiny microphones suspended among flowers, the team recorded the buzzing of the bees through all stages of the eclipse," reports Smithsonian Magazine. "The bees were active and noisy right up to the last moments before totality, the part of a total solar eclipse when the moon blocks all direct sunlight, and a night-like darkness settles over the land. As totality hit, the bees went totally silent in unison." From the report: The clear drop from buzzing to silence was the most striking change during the eclipse, but additional, smaller changes in the bees' buzzing could give the researchers clues about how the insects responded. As ecologist Candace Galen of the University of Missouri notes, the bees' buzzes lasted longer as it gradually got darker approaching totality. Increased buzz length suggests the bees started flying more slowly, they were taking longer flights, or some combination of both.

"The way I think about it is, if you're driving on a road and it gets foggy, you slow down," explains Galen. When there is less visibility, slowing down helps you process information and maintain situational awareness -- and like the bees did during totality, if there's absolutely zero visibility, you should probably pull over. Adjusting speed to acclimate one's senses to an environment that suddenly shifts is a common behavior in many animals, and it's been observed in bees when they fly before sunrise or sunset.
