Flys eye. Coloured scanning electron micrograph

Flys eye. Coloured scanning electron micrograph (SEM) of a flys (order Diptera) compound eye. The eye is made up of numerous visual units, known as ommatidia. Each ommatidium consists of an outer cuticle covering a lens, beneath which is a group of light-sensitive cells known as the retinula. Nerve fibres from the retinula converge onto the optic nerve, relaying visual signals to the brain. The image seen by a fly is thought to be a mosaic image, poorly focused but good at detecting movements

EDITORS COMMENTS
This print showcases the intricate beauty of a fly's compound eye. Through the lens of a scanning electron microscope, we are granted a mesmerizing glimpse into the world of these tiny creatures. The eye is composed of countless ommatidia, each resembling a visual unit with its own lens and retinula - light-sensitive cells responsible for capturing images. As nerve fibers converge onto the optic nerve, visual signals are relayed to the brain, allowing flies to process their surroundings. The image captured here reveals that a fly's vision is akin to viewing life through a mosaic filter; while poorly focused, it excels at detecting even the slightest movements. This unique perspective offers us an insight into how these remarkable insects perceive their environment. Beyond its aesthetic appeal, this photograph serves as an invaluable tool for researchers in fields such as zoology and biology. By studying the complex anatomy and sensory capabilities of flies' eyes, scientists can deepen their understanding not only of these particular insects but also gain insights into broader aspects of vision in other organisms. Thanks to Science Photo Library's expertise in scientific imagery, we can appreciate this false-colored masterpiece that combines artistry with scientific discovery. It reminds us once again that even within nature's tiniest creations lies extraordinary complexity waiting to be explored and understood.
