The Brown Argus (Aricia agestis) is a butterfly in the family Lycaeneide.
Although one of the "Blues" both sexes are brown on the uppersides with a band of orange spots at the border of each wing. They can be mistaken for other female blues but the Brown Argus never has any blue scales at the base of the wings like other female Blues often do. It could also be mistaken for the Northern Brown Argus Aricia artaxrexes were it not for the fact that their ranges do not overlap in the UK, unlike on continental Europe. The underside has the typical "blue" pattern of a greyish/brownish ground colour with black spots outlined in white and a row of orange spots along the border. The pattern of the black spots is the best way to distinguish this species from female Common, Chalk Hill and Adonis Blues since they lack the black spot found near the base of the forewing present on these three species. This species has seen an expansion in its range in recent years and is widely distributed across southeast England and most of the midlands with colonies occurring in Wales and as far north as Yorkshire. These northern sites have seen a lot of confusion in recent years with genetic studies looking at various colonies to separate the two Aricia spp. Up until a few years ago these northern colonies were thought to be the Northern Brown Argus and more colonies may yet be found to be misidentified. Like other blues it is common on the chalk downlands of southern England but will also use other habitats such as woodland clearings, coastal grasslands and heathland. It is widespread across Europe north to southern Sweden and eastwards to Siberia.
Common Rock-rose Helianthemum nummularium is the favoured foodplant on Calcarious soils. In other habitats Dove-foot Cranesbill Geranium molle and Common Stork's-bill Erodium cicutarium are used and possibly other Geranium spp. as well. Eggs are laid singly on the underside of leaves. The typically slug-like lycid larvae are green with a pale line along each side and always attended by ants. They hibernate as a fully grown larvae and pupate the following spring. There are two broods a year in the southern colonies with adults on the wing in May and June and again in late July till mid September but further north they are single brooded and fly in June and July.

Aricia agestis.
Piccolo licenide mancante di dimorfismo sessuale. Superiormente il colore di fondo è marrone scuro con lunule marginali arancione in serie completa. La pagina inferiore ha colorazione variabile dal grigio al bruno con punti neri cerchiati di bianco, assenti nella regione basale, ed una serie di macchie rosso-arancioni brillanti.
La specie sverna allo stato larvale. Ad aprile si hanno gli sfarfallamenti della prima generazione, a luglio-settembre quelli della seconda. Il bruco è tozzo e verde, con stria medio-dorsale porpora affiancata da tratti obliqui verde-scuro. Lo si trova spesso nei nidi di formiche con le quali stabilisce rapporti di simbiosi. Sue piante nutrici sono eliantemi, becchi di gru, gerani, centauree ecc., alla base delle quali avviene la ninfosi.
Dall'Europa (eccetto penisola Scandinava) fino all'Himalaia e alla Siberia. Presente anche in Nordafrica ed Asia Minore. Ovunque in Italia, dalla pianura ai 1500 m.

Hi Luciano,
Good evening neighbour! Beautiful composition, excellent macro. I feel the wing, especially the upper part, could be a little sharper, otherwise good shtuff. :-)
Kind regards from Ireland, László

Ciao Luciano, gran macro della deliziosa farfallina, dettagli al top, splendida nitidezza e magnifici colori, bravissimo, ciao Silvio

Wow another piece of art, well exposed and beautiful composed, nice click.

What a great ensemble of nature an excellent proportions by 3D work well done LUCIANO GOLLINI

Bonjour Luciano,

La végétation cadre bien l'insecte. La prise de vue permet de voir les détails du papillon Collier-de-corail. La lumière fait ressortir la beauté des couleurs. Bonne journée.

Pierre
