Thank you, all, for this discussion. I liked the fluorescent dye idea. I guess they are not storing pollen patty, but are storing a similar colored pollen. I am a brand new beek, so I already have so much to look for/at when I open the hive, and I don't want to wear out my welcome with the girls. So far, they have been very patient with my inspections, and repairing their wonky comb. What I should do is film my inspections, with a video cam on a tripod, so I can go back and look at some of the details I miss because I'm nervous and trying to not take too long.
