Compound eye of dragonfly. Macrophotograph of the compound eye of a dragonfly (species unidentified,order Odonata). The compound eyes of dragonflies consist of up to 30,000 individual facets called ommatidia. Each facet sends a signal to the brain,which then constructs a mosaic view of the world. The image lacks the detailed resolution of human sight but is good at dectecting movements. Dragonflies have unusually good sight for insects,enabling them to hunt on the wing | |
