False-colour SEM of the head of a housefly Featured 7 Jun 1990 Image

False-colour SEM of the head of a housefly

Coloured scanning electron micrograph of the head of a female housefly, Musca domestica. The head is dominated by the large compound eyes, here tinted yellow, which each contain around 4000 separate image-forming elements known as ommatidia. Each ommatidium is a cone-shaped structure consisting of a cuticular lens, a crystalline cone and an array of light-sensitive cells. The vertical, torpedo-shaped structures lying between the eyes are the fly's antennae. The feathery structure emerging from the centre of each antenna is a sensory organ known as an arista. Magnification: x9 at 35mm size. x15 at 6x4.5cm
