Spectral comparison of a Wild Strawberry (Fragaria vesca) flower in reflected visible light (top), ultraviolet light (middle) and infrared light (bottom).
The flower has a clear UV nectar guide pattern, with the petals appearing darker at the base in ultraviolet. The centre of the flower also appears much darker in ultraviolet.
In infrared the centre of the flower appears much brighter than it does under visible light.
