Tormentil in UV light. Tormentil (Potentilla erecta) flowers coloured to show areas that reflect (white) or absorb (dark blue) ultraviolet (UV) light. The bull's-eye pattern,known as a 'nectar guide',is thought to help attract pollinating insects,which can see in UV light. This image was taken on a digital camera adapted to filter and detect UV light. The resulting monochrome image was coloured on a computer. UV light is invisible to humans and does not have a true colour | |
