A really poor season of butterflies, perhaps the few rains and the heat of March have upset things, but I really find it hard to find something, there aren't even gnats ...

Order: Lepidoptera
Superfamily: Papilionoidea
Family: Lycaenidae
Subfamily: Polyommatinae
Tribe: Polyommatini
Genus: Polyommatus
Species: P. icarus

The Common Blue (Polyommatus icarus) is a small butterfly in the family Lycaenidae.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.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.

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.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.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.

Beautiful picture Luciano.
The light, color, sharpness and compo are great!
The moment is perfect too.
Congratulation!
Saludos.

Bonjour Luciano,

Le cadrage serré met l'insecte en évidence. La prise de vue permet de voir avec précision les détails du papillon Argus bleu. La lumière fait ressortir les couleurs. Bonne journée.
