Dragonflies are able to rotate their heads 360°
The image-filled, information-filled book Dragonflies: Magnificent Creatures of Water, Air, and Land in temperate and tropical climates achieves two dreams for Yale University Professor Pieter van Dokkum:
• applicability of dragonfly dynamics to observational astronomy; and
• record of dragonfly lifespans from birth to death.
Two 30,000-faceted compound eyes bring a dragonfly almost 360°-vision. The mechanics cause the Dragonfly Telescope Array's construction from 25 telephoto lenses clustered like one space-scanning, super-sized compound eye in New Mexico. They also dominate parts of the Yale University Press publication released in 2015 as the first complete photographic odyssey of the dragonfly, from deposited eggs to developed naiads to dead adults.
So photography and prose elucidate dragonfly forages, predators, prey, reproduction, and shelters.
