Washboarding. I don't know why they do it. I don't know of a good explanation of why they do it. Enjoy the mystery. They aren't doing anything wrong or harmful or indicative of anything, as far as I know.
Thank you, JW! Is it normal for a bunch of bees to sleep outside? Sorry to have so many questions. I appreciate all your help!This is called "washboarding" -- rhythmic forward and back motion with the head down. Its a inexplicable bee behavior, perhaps stimulated by the cedar hive. Other bees are fanning, drawing air through the hive with their wings.
Yes, it's normal.Thank you, JW! Is it normal for a bunch of bees to sleep outside? Sorry to have so many questions. I appreciate all your help!
