To correct that and see the ultraviolet patterns in these flowers, we need to use yet another filter. This filter blocks visible light and allows ultraviolet light to expose the film. The petals around the perimeter are reflecting the UV light. The perimeter ring reflects all colors of bee vision, including UV, so the ring appears as bee-white. Like paint on an airport runway, they essentially guide the pollinator to the reward.
Some pollinators are more olfactory than visual, and of course, some use both senses.
Flowers have evolved fragrances and this results in efficient pollinator attraction. Again, different animals have different sensibilities and sensitivities to fragrances. There is a plant called Sauromatum or Voodoo lily which has a stalk of flowers wrapped in a purplish-black leaf. It has evolved to be pollinated by flies. Humans are not as sensitive to fragrances as many other animals, and we certainly have not developed very good terminology to describe fragrances.
