I saw some yellow patches on the back of some of the girls inside the hive yesterday. It looked like they had been "marked" or painted not like pollen granules that settled on their back. I thought I read something a while back on this but cant remember what folks thought it might bee. Up here in Alaska I am still on my 1st supers and the rain season is nearing soon. it took forever to get them to cap it this cool season. Lots to learn up here in the frozen chosen!. Any ideas on the yellow patches?????
