POLYOMMATUS ICARUS MALE

Class: Insecta

Order: Lepidoptera

Superfamily: Papilionoidea

Family: Lycaenidae

Subfamily: Polyommatinae

Tribe: Polyommatini

Genus: Polyommatus

Species: P. icarus

Male uppersides are an iridescent lilac blue with a thin black border. Females are brown with a row of red spots along the edges. They usually have some blue at the base of the wings and, especially in Ireland and Scotland, are mostly blue but always have the red spots. Undersides have a greyish ground colour in the males and more brownish in the females. Both sexes have a row of red spots along the edge of the hindwings (extending onto the forewings though generally fainter, particularly in the males where they are sometimes missing altogether). There are about a dozen black centered white spots on the hind wings, nine on the forwings. The white fringe on the outer edge of the wings is not crossed with black lines as it is in the Chalkhill and Adonis Blues, an important difference when separating these species, particularly the females.
It is Britain's (and probably Europe's) most common and most widespread blue, found as far north as Orkney and on most of the Outer Hebrides. Males are often very obvious as they defend territories against rivals and search out the more reclusive females. A range of grassland habitats are used: meadows, coastal dunes, woodland clearings and also many man made habitats, anywhere where their food plants are found.
It is widespread in Europe, North Africa and temperate Asia.
Recently, Polyommatus icarus was discovered in Mirabel, Quebec, Canada by Ara Sarafian. An amateur entomologist, he had been observing the butterfly from 2005 to 2008. He contacted the Canadian National Collection of Insects in Ottawa where the butterfly was identified as P. icarus, a new alien butterfly to Canada and North America. The butterfly seems to be well established and is extending its range from year to year.
The main food plant on most sites is Bird's foot trefoil (Lotus corniculatus). Others used include Black Medick Medicago lupulina, Common Restharrow Ononis repens, White Clover Trifolium repens and Lesser Trefoil Trifolium dubium. Eggs are laid singly on young shoots of their food plants.
The caterpillar is small, pale green with yellow stripes and as usual with lycid larvae rather slug-like. Hibernation occurs as a half grown larvae. They are attractive to ants but not as much as some other species of blues. The chrysalis is olive green/brown and formed on the ground where it is attended by ants which will often take it into their nests. The larvae creates a substance called honey dew, which the ants eat while the butterfly lives in the ant hill. In the south of Britain there are two broods a year flying in May and June and again in August and September. Northern England has one brood flying between June and September. In a long warm year there is sometimes a partial third brood in the south flying into October.

POLYOMMATUS ICARUS MASCHIO

Descrizione
Piccolo lepidottero dallo spiccato dimorfismo sessuale. I maschi con ali superiormente blu e con riflessi violacei, margini soffusi di nero e contornati di frange bianche. Le femmine hanno livrea marrone con riflessi bluastri. Le parti inferiori, in ambedue i sessi, sono grigiastre o marrone chiaro, con macchie nere contornate di bianco e serie complete di lunule arancioni puntate di nero.

Biologia
La specie, svernante allo stadio di bruco, compare da aprile in poi con due o tre generazioni annuali. Le larve vanno alla ricerca di varie Papilionacee (gen. Medicago, Genista, Trifolium, Lathyrus, Ononis, Lotus, ecc..); si presentano verdi con linea medio dorsale più scura e fianchi percorsi a livello degli stigmi da una fascia biancastra. La ninfosi dura circa due settimane.

Distribuzione ed ecologia
L'areale abbraccia Europa ed Asia temperata, presente anche in Nordafrica e Anatolia. In Italia è specie alquanto diffusa dal livello del mare ai 2000 m. Nel territorio è tra i più comuni lepidotteri, lo si riscontra in cespuglieti, siepi e margini boschivi.

Ciao Luciano, bella P. icarus, magnifica la tonalità d'azzurro che si intravede, poi sto maschietto è delle parti mie e qui in umbria siam tutti belli...
ottima macro con magnifici detagli e splendid colori, danno un po' fastidio quei puntini bianchi sulla sinistra, comunque ottimo lavoro, poi anche questa a Pettino col freddo e il gelo, immagino, buon week end, ciao Silvio

Hello Luciano,
Beautiful colors and sharp detail from the spot on exposure. The composition and framing are flawless. A very good OOF backround keeps all your attention focused on the beautiful butterfly. Best regards Siggi

Ehee! Che bella la mia piccola colorata compaesana. Dovresti vedere in estate cosa c'è nel campo dove hai scattato questa! Ottimo dettaglio e buona luce anche se Silvio ha sottolineato, giustamente, i puntini bianci. Credo riflessi del flash sull' umidità che c'era.

Roberto

Very beautiful butterfly shot with great dexterity, Luciano.
Excellent details on the exposed wing. The glimpse of the blue on the upper wing promises a lovely colour on its open wings.
Well done and TFS.

Hello Luciano,
a very clear view for this capture. You did very well in giving the emphasis to the wings and its pattern.
The lghting is well controlled to give a lovely scene.

Hi Luciano,
A nice capture of this beautiful butterfly. Lovely sharp details and a nice composition. Thanks a lot for sharing.

Hi Luciano
a nice picture but too much flash, I think, there is little night mood over it.
The image is sharp with clean colors.
Did the butterfly caught in the spider's net?
Greetings
Gert

Ciao Luciano,
A fine capture of a male icarus.
The lighting and colours are superb and the sharpness almost perfect.
The dark leaf Bg shows this male up well.
A fresh specimen in the middle of October!
Wonderful and a fine way to show that your butterfly season is still with you!
Thanks and have a good weekend,
Ivan
