[S 6018] False-colour scanning electron micrograph (SEM) of the compound eye of a hoverfly, Syrphus ribesii. As with other insects, the fly's compound eye is composed of a large number of individual facets or 'ommatidia'. Each facet sends a signal to the brain, which then constructs a mosaic view of the world. The image is poorly focused but good at detecting movement. Magnification: x35 at 6x4.5cm size.
