My, what big eyes you have

The better to hunt you with, my dear. Compound eyes, each with 15,000 ommatidia, or single eyes, engulf the head and see in virtually all directions (ever tried sneaking up on a dragonfly?). With colour vision that outstrips our own, dragonflies can detect ultraviolet light, meaning that their eyes are acutely tuned to the light of blue sky and are very sensitive to tiny prey moving across it.
