A Pansy (Viola tricolor) flower photographed in visible light, ultraviolet light, and infrared light. There do not appear to be any UV visible nectar guides, but damage to the flower's petals is more obvious in UV. The markings around the centre of the flower are most prominent in visible light, but can still be seen in ultraviolet and infrared light as well.
