The same sunflower, a different perspective. The UV photo is false color: the camera turns ultraviolet into colors we can see.
To us it’s a plain yellow sunflower. To a bee, it has a bull’s-eye. The inner half of each petal is packed with UV-absorbing pigments called flavonols, while the petal tips reflect ultraviolet light. Bees can see that contrast, and it’s thought to steer them to the center.
