Species: M. jurtina

The Meadow Brown (Maniola jurtina) is a butterfly found in European meadows, where its larvae feed on grasses, such as Sheep's Fescue.
Similar species are Gatekeeper (which prefers to rest with its wings open) and Small Heath (which is smaller).
There is marked sexual dimorphism in this species. Males are less colorful, with smaller eyespots and much reduced orange areas on the upper forewings. They are also much more active and range far about, while females fly less and often may not away from the area where they grew up.
A variable number of smaller eyespots are usually found on the hindwing undersides. These may number up to 12 per individual butterfly, with up to 6 on each wing. The factors that govern polymorphism in this trait are not resolved, although a number of theories have been proposed (Stevens 2005). On the other hand, the evolutionary significance of the upperwing eyespots is more obvious: The more active males have a markedly more cryptic upperside pattern, whereas the females have more often opportunity to present their eyespots in a sudden display of colors and patterns that presumably make neophobic predators hesitate so that the butterfly has better chances of escaping.

MANIOLA JURTINA

Per il terzo anno consecutivo,la mia zona è stata invasa da migliaia di Maniole,ho fatto tantissime foto e penso che una rara con le ali aperte sia la migliore da mostrare.

Maniola jurtina (Linnaeus 1758)
Descrizione
Lepidottero di medie dimensioni caratterizzato dalla livrea marrone-scuro e con sulle ali anteriori un ocello preapicale con pupilla, presente anche sulla pagina inferiore ove spicca sul colore di fondo ocra. Le ali posteriori presentano, di sotto, una colorazione giallo-grigia più uniforme nel maschio, marcata, nella femmina, da una fascia postdiscale chiara contenente una serie di puntini scuri.
Biologia
La larva svernante riprende all'inizio dell'estate la sua attività compiendo subito dopo la metamorfosi. Generalmente un'unica generazione con sfarfallamenti che si protraggono per tutta l'estate fino ad ottobre. Il bruco ha tegumento verde-giallastro dorsalmente, più scuro ventralmente, con i fianchi percorsi da una linea biancastra sotto gli stigmi. Testa verde-bluastra. Conduce attività notturna nutrendosi di Graminacee (Poa, Agrostis, Bromus ecc.).
Distribuzione ed ecologia
Con alcune sottospecie copre un vasto areale che dalle isole Canarie si estende all'Asia Minore e all'Iran. In Europa si spinge fino alla Scandinavia. Presente ovunque in Italia (subsp. hispulla), dalla pianura ai 1500 m.
Specie comune nel territorio, ove frequenta ambienti assolati e campagne coltivate.

Hi Luciano,
Great exposure control and composition, but the butterfly, especially the left wings, could be a little sharper. Otherwise a fabulous photo in your unmistakable style.
Kind regards from Ireland, László

You caugt one who fought in WWII. It has been through a fight or two. You certainly bring it out.

Good capture of this slightly tatty butterfly with its wings open, Luciano.
I find the focus pretty good and the colours most natural.
I guess I too captured a Satyrinae during my recent trek to Himalayas which I will post here next.

Hello Luciano,
A little tattered, but still an attractive specimen you have presented to us. The sharpness to me looks fine and the exposure is right on the money. Nicely shown against a BG of lovely green foliage. Reminds me of the Little Wood Satyr we have here in Ohio.

Ciao Luciano, ti meriti un -2 e una nota sul diario, almeno postale sana....Per questa volta sei perdonato, ma non ci riprovare, ciao Silvio

Hello Luciano,
Beautiful picture of this butterfly. I like its POV and composition. To me sharpness looks nice although I use bit extra sharpness when post small size picture in web.
Thanks and cheers!
Srikumar

Bonjour Luciano,

La végétation cadre bien l'insecte. La prise de vue permet de voir les détails du papillon Myrtil. La lumière donne un bon rendu aux couleurs de l'image. Bonne journée.
