No! They just happen to be fluorescent thanks to science! This experiment discusses the ways to track bees for ecological purposes and compares fluorescent powders to protein powders. The bees were marked using a tube placed at the entrance of the beehive that would coat the bees in either a fluorescent powder or a protein powder made with egg whites or powdered milk as they leave. This allows for scientists to track where bees are for the purposes of counting populations, determining spread of pollination, and many other tracking reasons.
The paper determined that the fluorescent powders were significantly more accurate in coating the bees than the protein coatings and was easier to recognize later as well as produced a lower false positive percentage. This method of marking bees could be used widely in ecology and is an important look into the ways we can continue to SAVE THE BEES!
