Caption: Striped squill in UV light. Striped squill flower (Puschkinia scilloides) photographed to show areas that reflect ultraviolet (UV) light (base of petals) or absorb UV light (fused stamens at centre of flower). The UV 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. UV light lies outside the visible spectrum, hence it has no true colour. The monochrome image resulting from the camera is coloured on computer. See image B830/3465 for the same plant in normal daylight.
