Compound eye of a gnat, SEM
Compound eye of a gnat. Scanning electron micrograph (SEM) of the surface of a compound eye from a fungus gnat (suborder Nematocera). 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

EDITORS COMMENTS
This print showcases the intricate beauty of a compound eye belonging to a fungus gnat. Through the lens of a scanning electron microscope (SEM), we are granted an up-close view of this remarkable structure. Composed of numerous rounded lenses called ommatidia, each serving as a simple eye, this compound eye plays a crucial role in the gnat's visual perception. As light enters through these lenses, signals are transmitted to the gnat's brain, where they merge together to form a mosaic-like image of its surroundings. Although not particularly sharp, this unique vision is highly adept at detecting even the slightest movements in its environment. Between these lenses lie delicate hair-like structures known as interommatidial bristles, further enhancing the complexity and functionality of this ocular masterpiece. The monochrome nature of this image adds an artistic touch while emphasizing the intricate patterns and textures found within. Through this mesmerizing photograph, we gain insight into the fascinating world of insects and their extraordinary anatomical adaptations. It serves as a testament to both the wonders of biology and our ability to explore them through advanced imaging techniques like SEM.
