|[Note Guidelines] Photographer's Note|
|Odonate larvae are non-discriminate hunters which will eat any animal as large as or smaller than themselves, including their own species. Small vertebrates such as tadpoles and fish fry are not immune from attack. Prey may be stalked or ambushed. Captured prey is pulled back using powerful muscles in the labium and chewed by strong mandibles. More details on labium structure and larval predatory activity are available.|
Almost all odonate larvae are aquatic. They occur in every sort of water body from soaks and seepages to streams and rivers, lakes, temporary pools and water-filled tree holes. A few species tolerate moderate salinity, a few others have semi-terrestrial larvae which roam across the surface of bogs and swamps at night. A half-dozen or so fully terrestrial larvae are known from distantly related families. These animals live in leaf litter layers in tropical rainforests.
As they grow, larvae undergo approximately 10-20 molts, over a time between 3 months and about 6-10 years depending on species. Instar number is not always fixed but may depend on seasonal conditions and food supply. Wing pads develop externally from about the 6-7th instar. Metamorphosis is direct without a pupal stage and emergence takes place on a fixed support out of the water, sometimes a considerable distance from the water's edge. The newly emerged adult flies away from water for a few days to feed and mature, during which time the full adult color develops. Teneral (new) adults can be recognised by a glassy sheen of the wings. Additional color changes occur later in life in some species.

Hello Sergio, I see we are neighbors today.
It is a cold dreary day here in Ohio, so there is no chance of photographing any insects such as this.
You have photographed this particular dragonfly larva perfectly as it emerges from it's exoskeleton. Every minute detail is easily viewed in beautiful natural colors. I love the way the eye appears so shiny and clear. A gorgeous shot indeed Sergio!!!
great composition with good details and beautiful colours
thanks greeting lou
