The same species that I posted recently, but in the more rare Helice shape with more vivid colors. You can see the differences compating with my last post.

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.

Hello Luciano,
Another wonderful close-up image of a fine looking Clouded Yellow. I went back and forth comparing this and your previous image and there really is quite a bit of difference in color tones and markings. To tell you the truth they both have their own distinct characteristics, therefore I can't say I like one over the other:) Great work!!

Ciao Luciano,
Nicely composed photo, but there are - in my opinion - certain issues which should have been rid of. For example the blown out patches and the halfly cropped flowers at the top, or the background noise. I found the contrast too few also, and the focus a bit soft (probably due to the re-sizing procedure as your file size was only 98 KB, very far from the 300 KB limit). I made a quick WS to demonstrate the above.
Kind regards from Ireland, László

Hello Luciano – Very attractive picture of this Colias crocea with an excellent lateral view showing us all the details of the back from the wings. Activity of the butterfly collecting the nectar on the flower properly caught.

Technical achievement

• Excellent focus on the wings and in the same times on the small inflorescence
• Perfect exposure with an appropriate choice of aperture/speed and iso.
• Perfect depth of field and sharpness – The lateral view is a good choice
• Contrast could have be better
• Excellent sharpness showing all the details of the wings and the proboscis in action inside the flowers; again a better management of the contrast would have drastically improve the impact of the picture
• Precise white balance and exact colour rendering for the butterfly and the flowers
• Probably post processing to improve in order to magnify your snap
• Good background blur even if the noise could have be improved during the post processing.

Impact

• Interesting picture with a combination of the two world (insects and flowers); very good capture.
• Efficient framing and composition with an appropriate disposition of the subject inside the frame. Dynamic composition in diagonal. Only a small, small, small point: not easy to distinguish the two antennas; and another point: in my personal opinion, it will have be better to resize the picture in order to remove the leaflets and small flower around the frame.

Thank you for the sharing.

Have a good day.

Philippe

Ciao Luciano
