Sulphur cinquefoil in UV light. Sulphur cinquefoil (Potentilla recta) flower in ultraviolet (UV) light. The bull's-eye UV pattern is a result of the flower either reflecting UV (light areas) or absorbing UV (dark areas). This pattern is known as a 'nectar guide' and is thought to attract insect pollinators that can see in UV light. This image was taken on a digital camera adapted to filter and detect UV light. The resulting image appears monochrome since UV light has no true colour. See image B830/3456 for the same flower seen in daylight.
