, hand held.

Scatto tecnicamente molto difficile per via dei riflessi, in quanto l'esserino è quasi interamente avvolto dall'acqua... La brevità della vita degli adulti è compensata da un lungo processo di sviluppo larvale. Alcune larve arrivano ad impiegare 2 anni per raggiungere la prima muta (Ephemera danica), anche se la media rimane quella di un anno. Le larve di alcune specie posseggono ben 27 mute. Il loro sviluppo avviene completamente in acqua, o comunque nelle vicinanze della superficie. Si nutrono di piante ed alghe, e si ipotizza che alcune siano in grado di cibarsi di composti organici animali. Respirano grazie a branchie laterali appiattite, dette tracheobranchie (di solito 7) disposte lungo l'addome, anche se non mancano specie con branchie situate alla base delle coxe. Gli Ephemeroptera prediligono acque non inquinate, esenti da grandi quantità di residui organici. Non a caso sono spesso considerati indicatori ecologici utili a ricavare immediatamente informazioni sulla salute dell'ambiente circostante.

Taking obtained with the total respect of the larva, taken from their natural environment thanks to the expert knowledge of Umberto The Deaf (thanks) was constantly wet just to recreate its condition. Completed the shots, the larvae were gently placed where they can safely continue their vital evolution. Unfortunately, in many cases in the macro as well all know it also comes to the killing of the subjects, well, I wanted to let everyone know that in my case, even at the cost of returning home empty-handed, never would I dare to find solutions to similar ...
With this, I wish you a happy 2012 in total respect of nature!

reflections for me, undoubtedly intrusive, help to read the scene revealing the presence of water ...

nice intro (not longer than that or people likely to skip a footer equal ... :-) ;-))
