"'In the early evening the dragonfly nymph climbs to the top of a reed. She then bends her abdomen while breathing in air, cracking open her skin right below the head. The dragonfly emerges headfirst and upside down. Hanging from the nymph shell, she has to wait until her legs harden before she is able to crawl out and turn around. In the space of about 15 minutes she extends her wings by pumping air into them. Over the next three to four hours her abdomen slowly extends and hardens. Shortly before dawn she spreads her wings. With the first light of the sun the newly emerged dragonfly takes off on her maiden voyage, leaving her old life (and skin) behind."
