Why are bees on the outside of my hive?

Why my bees are on the outside of the hive.

I flinched when that 1st bee flew past the microphone 😂 I had my headphones on..

A great topic . Last summer i shaded my hives with an old trampoline and was surprised at how much more comb was being drawn out, when it gets too hot the wax will not stiffen , so they quit drawing comb..........

Does the trampoline let enough light through to keep the wax moths away?
