Flowers in the UV

Honey bees have eyes with spectral sensitivitiy in the yellow, blue and ultraviolet (UV). Amongst these colour groups, the power to distinguish shades of colour is sharpest in the UV. \r\nThis site shows picture of flowers in the UV, how bees would see them, and explains the method that the photographer used to take the UV pictures.

Flowers in Ultraviolet

UV fluorescence is not a common trait to most flowers, although pollen grains occasionally are seen to fluoresce. However, quite strong fluorescence has been noted from nectar glands (Angelica sylvestris) or anthers (several species).\r\n\r\nThis site lists and shows pictures of plants that fluoresce in UV light. It also explains what is going on and gives an explanation.
