About this image

Coloured scanning electron micrograph of the surface of a single grain of pollen of an Evening Primrose (Oenothera sp.). This part of the sample is about 50 micrometres wide. The very high magnification shows that the pollen grain has very fine hairs (white) made of viscin that allow the grain to grip the body of a passing insect for transport to another flower. These threads mean that the pollen may often only be transported by an individual species of bee. There are about 125 species of Evening Primrose, each adapted to be pollinated by a particular type of bee. This image was created in monochrome then digitally colourised.
