Horse fly eye. Coloured scanning electron micrograph (SEM) of the compound eye of a horse fly (Tabanus sp.). The eye is composed of numerous facets (ommatidia),each of which contains a lens. Beneath each lens are retinal cells,which send nerve signals to the optic nerve. Each ommatidium gives a tiny image of part of the horse fly's field of vision,resulting in a detailed mosaic image. Female horse flies feed on the blood of horses,humans and other large mammals. Magnification: x90 at 6x7cm size | |
