Metamorfosi
The larva, which is about to change, it begins to leave the water for periods of time always longer breathing gradually through the stigmas chest and finally comes out and finally climbs on a support.
Here starts the flickering, similar in all species, with the drying of the cuticle that, exposed to air, breaks dorsally to the chest, so it appears at first the head, followed by the chest with his legs, and finally , from the first abdominal segments.
Once freed from the old cuticle begins to stretch its wings, which were folded in pteroteche, relax the abdomen completely, reaching its final size.
Throughout the period of metamorphosis lasted for a few minutes to about two hours. Generally takes place in the early hours of the day although in some species occurs at night.

Metamorfosi
La larva, che si appresta a mutare, comincia ad abbandonare l’acqua per intervalli di tempo sempre più lunghi, respirando progressivamente tramite gli stigmi toracici; infine ne esce definitivamente e si arrampica su un supporto.
Qui ha inizio lo sfarfallamento, simile in tutte le specie, con il disseccamento della cuticola che, esposta all’aria, si rompe dorsalmente all’altezza del torace, così emerge per prima la testa, seguita dal torace con le zampe, e, infine, dai primi segmenti addominali.
Dopo essersi liberato dalla vecchia cuticola inizia a distendere le ali, che si trovavano ripiegate nelle pteroteche, l’addome si distende completamente, raggiungendo la sua dimensione definitiva.
Tutto il periodo della metamorfosi dura da qualche minuto a circa due ore. Generalmente ha luogo nelle prime ore del giorno anche se in qualche specie avviene di notte.

Hi Sergio. This is a fine picture showing the dragonfly leaving the larva. It will be a time now to pump up the wings. and to warm up in the sun. This is a fine side view so we cansee both so well with good detail and natural colours. well done TFS.

Hi Sergio,
A nice capture of this metamorphosis phenomena of dragonflies. Very good sharp details and a lovely composition. Thanks a lot for sharing.

Buona cattura amico Sergio

Penso che la luce ambiente è stato un po 'difficile da gestire. Ma si sa dare una immagine molto buon equilibrio e lunghezza. Inoltre, catturato il momento della schiusa.

Buon lavoro, saluti e felici Domenica,

Jesús

Ciao Sergio,
un'altra delle due interessanti immagini sulle straordinarie trasformazioni di questi insetti, io ho sempre trovato solo la parte secca e non ho ancora assistito allo sfarfallamento, buona definizione e belli e naturali i colori.
Grazie e complimenti
Ciao Maurizio
