Thanks for posting Don! I have observed some of this behavior before. A queenless hive acts like they don't have a "mission". While a queen right hive comes and goes efficiently like time is precious. The only time I ever observed a K wing pattern was a hive I suspected of getting into some type of insect spray. I didn't lose the whole colony, but I had a lot of disoriented bees dying at the entrance on the ground. They were displaying the K wing formation and spinning on the the ground.
I would be interested in hearing if anyone has noticed the general mood of a queenless hive being different. I don't want to hijack the thread, just interested in comments.
