Hello friends,
Today it's a shot of a fairly frequent butterfly that graces our countrside; The Clouded Yellow, Colias croceus, is a small butterfly of the Pieridae family, that is, the Yellows and Whites.
Easily identifiable by the bright yellow colouring, much brighter than that of the lemon yellow male Brimstone. The upperside is golden yellow with a broad black margin on all four wings. The underside has a more greenish tint to it and lacks the black borders. In the center of the underside hindwing is an obvious white spot. Females differ from the males in having yellow spots along the black borders on the upperside. Like all Colias sp. they never open their wings at rest. In a small proportion of females the golden upperside colouration is replaced by a pale cream colour, form helice, which can be confused with the rarer Pale Clouded Yellow Colias hyale and Berger's Clouded Yellow Colias alfacariensis. Helice tends to be more heavily marked in black.
Clouded Yellows breeding range is North Africa and southern Europe and eastwards through Turkey into the Middle East but It occurs throughout much of Europe as a summer migrant, in good years individuals reaching Scandinavia. In the UK they can be seen on the south coast almost every year in varying numbers where they regularly breed. Occurrence in the rest of the UK varies considreably from year to year.
A truly migratory European butterfly, this species is famous for occasional mass migrations and subsequent breeding, which are often referred to in the United Kingdom as 'Clouded Yellow Years'. Notable clouded yellow years include 1877, 1947, 1983, 1992, 1994, 1996 and 2000.
In southern Europe and North Africa they breed continuously throughout the year.
Eggs are laid singly on foodplant leaves.
The caterpillars grow fast in warm weather, sometimes pupating within a month.
Pupation lasts for two or three weeks and in good years there can be as many as three broods in a year in th UK with adults still on the wing at the beginning of November.
Clouded Yellows feed on a variety of leguminous plants. In the UK wild and cultivated clover Trifolium spp. and Lucerne Medicago sativa are favourites and less frequently, Common Bird's-foot-trefoil Lotus corniculatus. Description directly from Wikipedia.
Camera was hand held when the shot was taken and with the Raynox up front. I used some fill flash because at F11 I had to underexpose in order to attain an acceptable shutter speed.
Hope you like the shot and thanks for looking.

Hi Mark,
Beautiful image; especially through its colours for example the whites (flower) and the yellow (butterfly).

Hello Mark,
Very fine capture of this Clouded Yellow. I like its pose on the white thistle. All sharply in focus showing sharp details and lovely colours which stand out against the brown background.
Many thanks, Ulla

You have presented the Clouded Yellow in all its glory in this shot, Mark.
The composition with the flower is simply outstanding.
The focus is spot on and the details and colours truly exquisite.
Well done and thanks for sharing this beauty.

Hi Mark,
I like the classic side view and the deep well saturated color. Sharpness and exposure are outstanding. I think there is chance this could be Orange Sulphur which is very difficult to distinguish from Clouded Sulphur unless you see them with wings open. The orange Sulphur has a orange spot on upper side of wing. The Clouded Sulphur does not. Very nice shot!

Hi Mark,
Beautiful Clouded Yellow. Very nice composition. The blurred background gives depth and stands out this Clouded Yellow. Well done image.

Hola Mark,
Una bonita presentación de esta bella mariposa. Saludos
José Ramón
