“Dragonflies have the largest eyes in the insect world, with up to 30,000 facets, and wrapping entirely around their head so that they can see in all directions at once. Close up, their eyes have multicolored iridescence, a little reminiscent of the colours on a compact disc, but with a three-dimensional, almost holographic, effect.”
