Blue-eyed hook-tailed dragonfly

Onychogomphus uncatus

''Onychogomphus uncatus'', the large pincertail or blue-eyed hook-tailed dragonfly, is a species of dragonflies belonging to the family Gomphidae.

This dragonfly is bigger and rarer than the small pincertail. It is present in Belgium, France, Germany, Italy, Spain, Portugal and Switzerland.
Ecdysis - emergence of a dragonfly After a few moults, or ecdysis - moulting of the cuticle in invertebrates - a new (re)born dragonfly slowly emerges from its last exuviae... during its emergence haemolymph is pumped throughout the entire body especially to the wings, which causes them to expand to their full extend.

This series were captured during the field work for the IUCN red List, 
and just for a brief short, because there's never enough time to spend on this observations :)
