What's on my tray?

I found this debris on the tray. It is there pretty much every day. What are the girls up to? Thanks, Ray

That looks like fecal matter or dark wax cappings from when brood chew their way out. Also if that is all you have on the bottom you are in good shape.

Here is a bottom that is not in good shape.

Could be wax.  Could be Varroa. It's too out of focus to tell.  :)
