Chris said "On the very rare occasions that I feed my bees with syrup I usually add some blue food dye to make it obvious if any ends up in the honey. I wonder whether somebody near you is doing the same." Did your blue tracer reveal anything interesting about how the bees use/distribute the syrup? Did post-feeding supers end up with any blue honey? Chris *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
