I didn't go back down until 4:30 and it's all over now but the shouting. Here's what it looks like now:
Amazing, what quick work they made of cleaning up the comb. There are still bees in the filter with the dark comb in it. It's stacked pretty deep because it is the wax from one 8 frame super. So the bees burrow down to get the drips of honey.
We have NO nectar at all right now, so they were thrilled for this opportunity. I'm sure bees came from all around. I could see their flight paths as they flew from the back to the front of my house, so clearly they were not in any way all from my hives.
