Sounds like this poster's bee's are within flying distance of one of those trailer heavens that used to be so popular in Florida and other places. Here in California natural propolis is in short supply most of the year and the bee's will bring in all kinds of man made propolis. From grafting wax, to green paint off of out houses. The all must have some oil, like linseed oil that makes them attractive. The bee's will also rob propolis off of exposed bee equipment, and clean all the wax off of new frames not stored inside. I have seen them do a job on some stacked in the back of a open garage/workshop with the door open. Bee equipment from other states that do have LOT's and lot's of propolis so bad you can't get the frames out will be clean in one season in this part of California which proves that, at least to me, that propolis is indeed consumed by the bee in more activity then just sealing up the hive for winter. I suspect it is used to varnish or coat the inside of brood cells and plays some part in the health of the bee grub, or it could just be a engineering thing to hold the heat in the brood area. I do know for sure it disappears and that bee's hear about's spend much time working on substitutes for it. ttul Andy- --- ~ QMPro 1.53 ~ Bienenzuechter
