Colias Crocea.
A regular migrant to the Uk from Europe, and although seen in most years it is well known for occasional "mass" migrations, sometimes called "Clouded Yellow years". Usually seen from March to October. Found in fields, meadows and grasslands over much of North Africa and Southern Europe to the Middle East, occasionally reaching the Scandinavian region when migrating. Feeds on leguminous plants, including the Clovers (Trifolium), Lucerne (Medicago sativa) both found in Brickfields Park, and occasionally, Common Bird's-foot-trefoil (Lotus corniculatus). Breeds in the Uk but does not overwinter. The caterpillar is bright green and hairy with a broad pale yellow / white stripe along its upper side. Capable of two broods per year usually in June and August.
With a wingspan of 50-65mm (2-2.5in), when settled it always has it's wings closed so the greenish yellow undersides with central silver spot outlined in red are the usual view of this butterfly, however the wing upper sides are an orange-yellow with broad dark brown borders, in the female ♀ these borders contain yellow or pale white spots. A small proportion of females are pale yellow and can be confused with the rarer Pale (C. hyale) and Berger's Clouded Yellows (C. alfacariensis). Females are larger than the males ♂, both having a dark brown spot to the upper forewing whilst on the upper hind wing the females have the same central silver spot outlined in red as the underside which is absent in the male.


COLIAS CROCEA
Descrizione
Lepidottero di media grandezza dalla livrea giallo-arancio con larghe fasce marginali nel cui interno, ma solo nelle femmine, sono comprese macchie gialle. Le parti inferiori sono di colore giallo-citrino con una coppia di punti bianchi contornati di rossiccio sulle ali posteriori. Queste ultime presentano, inoltre, una serie di punti scuri nella regione postdiscale. Non di rado si osservano femmine dalla colorazione bianco-verdastra ascritte alla forma "helice", fissata geneticamente.
iologia
Sverna come bruco nascosto tra anfratti e sotto le pietre. In primavera avviene la metamorfosi in crisalidi succinte provviste di un appuntito processo cefalico. A partire da maggio e fino all'autunno, si susseguono varie generazioni. Piante nutrici sono diverse Leguminose e soprattutto le vecce, sulle quali vengono deposte uova rosso-arancio.Distribuzione ed ecologia
Diffusa in Europa centro-meridionale, Nordafrica e Asia minore. Ovunque in Italia, dalla pianura ai 2400 m. Specie tra le più comuni nel territorio, ove si riscontra con frequenza nelle campagne coltivate e al limitare dei boschi.

Nice shot Luciano, great colours, and exposure. It's good to see the habitat in the background. I am fascinated by the crazy eyes of butterflies, thanks for sharing, Moz

Hi Luciano
This species does not look so different from others that I have seen in my country.
As usual the exposure and sharpness are the best. Good work.

Regards

Bonjour Luciano,

Les fleurs cadrent bien l'insecte. La prise de vue permet de voir les détails du papillon Souci. La lumière fait ressortir la beauté des couleurs. Bonne journée.

Pierre

Ciao Luciano, questa me l'ero lasciata via, un po' anzianotta, ma i colori sono ancora brillanti, esaltati dal contrasto col fiore, ottima nitidezza e magnifici dettagli, bravissimo, ciao Silvio
