About this image

Scanning electron micrograph of the front leg of a male fruit fly (Drosophila melanogaster) showing the sex comb. This is a secondary sexual characteristic of the fruit fly that may be used to hold the female during mating. It is a rapidly evolving structure in D.melanogaster and the size and number of bristles appear to be important in selection by females. This image was captured in monochrome then later digitally colourised. PS Micrographs, Powys, United Kingdom
