Cicada, Out of Nymphal Shell and Hardening into Adult Flyer - I picked these two stages at random and the adult did not come from that shell

 adult cicadas shed the nymphal exoskeleton, which is left behind, in an hour or less and at that point are soft, white, and unable to fly as the exoskeleton takes a few hours to mature and harden - once hardened the adults are capable of flying but are rather clumsy fliers and often collide into objects.
