Light micrograph of the compound eye of a bluebottle fly, Calliphora vomitoria. 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 movements. The resolution of the movement that can be detected depends on the number of ommatidia. A bluebottle has 5000 ommatidia, a dragonfly 30,000. Magnification: x400 at 35mm size.
