The exuvia is the empty skin, or carapace, of the last larval stage (final 'stadium'). When the larvae is ready to metamorphose, it first climbs out of the water (generally on emergent vegetation); then the carapace splits along the back and behind the head and the immature adult emerges. You can find these exuvia on the vegetation as evidence of their emergence. The exuvia in this picture is on yellow flag (Iris pseudacorus).
