Compound eye. Scanning electron micrograph one of the large compound eyes (red) of a caddis fly (order Trichoptera). Each compound eye is made up of numerous simple eyes called ommatidia. Each ommatidium sends a signal to the fly's brain,which combines the thousands of images to form a mosaic view of the world. The image is not sharp but is excellent at detecting movement. Caddisflies are moth-like insects but have hairy wings rather than the scaled wings of moths and butterflies | |
