Ephemera danica (M?LLER, 1764) Dimensioni: apertura alare mediamente sui 12 mm. Descrizione della specie: L'ordine degli Efemerotteri o Effimere comprende insetti arcaici, conosciuti già dai tempi antichi per la brevità della loro vita allo stato di adulti, da cui il nome di Ephemeroptera (dal greco ephemeros=che vive un giorno). Gli adulti sono terrestri, ma le forme larvali e ninfali, la cui vita può durare fini a tre anni, sono acquatiche L'insetto adulto è caratterizzato da brevi antenne filiformi, apparato boccale atrofizzato, ali posteriori ridotte e un lungo addome terminante con due o tre filamenti composti da numerosi articoli. A riposo, le ali sono mantenute in posizione verticale cioè non possono essere ripiegate sul corpo. Le larve e ninfe sono dotate di un apparato boccale ben sviluppato, di tipo masticatore, frequentano le acque dolci correnti e stagnanti. Lo stato adulto è preceduto da uno stadio di "subimmagine" alato.Gli adulti non vivono più di qualche ora, il tempo di compiere il volo nuziale, preceduto da danze aeree per i maschi e seguito immediatamente dalla deposizione della femmina, che lascia cadere le uova sulla superficie dell'acqua. L'accoppiamento avviene in aria, anche se gli insetti accoppiati spesso cadono sul terreno o in acqua. La femmina muore subito dopo la deposizione, ma è comunque sopravvissuta più a lungo del maschio. Nel corso della loro vita gli adulti non assorbono alcun cibo e il loro apparato digerente è trasformato in un organo aerostatico. Le larve e le ninfe, invece, si nutrono soprattutto di particelle vegetali, alghe microscopiche o detrito. Questi insetti sono inoffensivi e offrono un abbondante nutrimento ai pesci e ad altri animali acquatici. Infatti la comparsa delle Effimere è stagionale e pesci ed uccelli sono in grado di compiere previsioni sulla loro comparsa e di prepararsi ad un lauto banchetto offerto loro da questi insetti. Distribuzione e habitat: frequentano le acque dolci correnti e stagnanti. In Europa sono presenti 14 famiglie (su 19 distribuite in tutto il globo, eccetto che in Artide e in Antartide) suddivise in circa 200 specie, di cui 80 vivono in Italia. Periodo di attività: Negli Stati Uniti gli Ephemeroptera prendono il nome di Mayfly, ovvero letteralmente "mosche di maggio" (nonostante sfarfallino anche in altri periodi).

Subject is very beautiful, I've never seen.
I guess, to treat so good alignment, you been there a good hour ...

Execution would say very good, even though you know the backgrounds so empty I bring anguish.

Interesting description, for the drafting of which I venture a suggestion: do not write everything below, but breaks lines between them, even with empty lines.

As it is now, it looks like a single block, for more small character, who may scare some brave who would be curious to know who you've photographed.

PS
Bride yes, but I do not see the veil is Muslim ?? :-D

Many thanks to all, very welcome your comments and suggestions :)
Maurov For the description I made a copy and paste from my pc, I have not noticed the writing:-D I'll try to do it as you suggested, although not easy, I think the system affects everything attached by default, then try ;-)
a greeting to all and good weekend:-)
