A new study suggests that bees can store information in long-term memory while they sleep, just like humans do when we dream.

Similar to our circadian rhythm, honeybees sleep between five and eight hours a day. And, in the case of forager bees, this occurs in day-night cycles, with more rest at night when darkness prevents their excursions for pollen and nectar.

Without a good night’s sleep, then, honeybees start to forget the activities that should be second nature to them. And in a study released in 2015, Randolf Menzel and his colleagues from the Free University of Berlin provided a possible explanation as to why this might be.
