[Note Guidelines] Photographer's Note
What you see here is not an alien, but the empty shell (Exuvia) left behind when a dragonfly emerges from the water to turn into the winged Teneral form of the Common Darter (Sympetrum striolatum)see the adult forms here.
It is seen here on a reed at the edge of a very small fresh water pool 5metres across in amongst some sand dunes on the west coast of England,The whole series of dunes are an (SSSI) Site of Special Scientific Intrest more details here .Most of these pools dry out over the summer as they are only filled with winter rain water, these tempory pools are used by the Natterjack toad to breed in. These very rare toad are the main reason why the site has the SSSI status, I am afraid there will be no pictures of the toads as their protection level extends to them not having their picture taken without a goverment licence.

Una imagen distinta de estos insectos tan conocidos ya por nosotros.
Excelente idea de mostrar el shell del insecto de esta forma.
Buen encuadre y colorido, solo remarcaría la existencia de ruido en el fondo de la imagen.

An image different from these insects so known already by us.
Excellent idea to show the shell of the insect of this form.
Good colorful and frame, only remark the existence of noise at bottom of the image.
(points tomorrow)

Nice and sharp capture. When seeing one up close like this it's hard to imagine that in real life they're only about 1½-2 cm long. I hope you did get to see him emerge, too, it's quite an interesting experience ;-))

A most unusual subject and yet you have captured it very well, the DOF and POV are just great. Yet another image for you to be proud of Rob.
