Compound eye of a gnat, SEM
Compound eye. Coloured scanning electron micrograph (SEM) of the surface of a compound eye from a fungus gnat (family Sciaridae). The eye consists of many rounded lenses known as ommatidia. Each ommatidium is a simple eye that sends a signal to the gnats brain. All the signals are combined by the brain to form a mosaic view of the world. The image seen is not very sharp but good at detecting movements. Between the lenses are hair-like structures called interommatidial bristles. Magnification: x850 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a compound eye belonging to a fungus gnat. The image, captured using a scanning electron microscope (SEM), reveals the fascinating structure and function of this remarkable organ. Composed of numerous rounded lenses called ommatidia, each acting as an individual simple eye, the compound eye sends signals to the gnat's brain. These signals are then combined by the brain to create a mosaic view of its surroundings. Although not exceptionally sharp, this compound eye excels at detecting movements in its environment. Between the lenses, delicate hair-like structures known as interommatidial bristles can be observed, adding another layer of complexity to this optical marvel. The vibrant orange hues in this false-colored image add an artistic touch while highlighting different anatomical features. This photograph provides valuable insights into insect vision and serves as a testament to nature's incredible diversity and adaptability. Displayed at 10 centimeters wide with an impressive magnification factor of x850, this print from Science Photo Library offers viewers an up-close encounter with one of nature's most extraordinary creations – showcasing both its biological intricacies and aesthetic appeal.
