A dragonfly shedding the integument it wore as a nymph. The nymphal shell will remain as the exuvia. The white filaments hanging out of the exuvia are the linings of the tracheae, showing that they too are part of the integument.
This dragonfly has left its slate-grey exuvia and is expanding its new, soft integument to full size before it hardens. Note that the exuvia shows every detail of the external anatomy of the nymph, including eyes, mouthparts, antennae and bristles


From Latin exuvia, from exuō (I take off).
