Facing a whole hive of bees at once can be overwhelming—even for a bee. Young honeybees sleep more after spending time in the hive than after being by themselves. They need the extra nap time, it seems, to build and maintain their learning brains.
The first surprising thing about this might be that insects sleep at all. “Since around the 1980s there is good evidence that insects show…characteristics of sleep,” says Guy Bloch, who studies bee behavior at the Hebrew University of Jerusalem.
