Bee behavior on outside of hive

I am wondering what the bees are doing on the outside of the hive? It’s about 6:00pm in South Florida…87 degF

Is this normal behavior? Is this productive for the hive?

Are they rocking back and forth? I’ve learned on this forum that this is called washboarding, a behaviour performed by adolescent bees and not yet fully understood.

Thank you!

I think you are right…It did seem as though they are cleaning the wood surface…I will have to watch more closely tomorrow…

Thanks again!
Michael
