Most insects have multifaceted eyes—house flies, for example, have about 6,000 eye facets that give them a panoramic view of their surroundings. It’s the reason their eyes look like honeycombs up close. But with 30,000 individual facets, dragonflies blow them—and every other insect—completely out of the water. Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture.
