Clouded Yellow Colias croceus

ab. cremonae Verity 1915

These are all forms of the male with the ground colour of a decided yellow instead of the normal orange.

They vary in tint from sulphur-yellow to greenish-yellow.

It is almost impossible to tell from the authors original description just what shade is described.

ab. nigrofasciata Verity 1909

On the forewings there is a black streak or wedge from the black marginal band to the discoidal spot

ab. nigrofasciata Verity 1909

On the forewings there is a black streak or wedge from the black marginal band to the discoidal spot

ab. nigrofasciata Verity 1909

On the forewings there is a black streak or wedge from the black marginal band to the discoidal spot

ab. nigrofasciata  Verity 1909

On the forewings there is a black streak or wedge from the black marginal band to the discoidal spot

ab. retracta Kitt 1924

The black marginal band on the male forewings extends along the inner margin as far as the middle of the wing or beyond.

ab. basisuffusa Lempke 1933

Female with the base of the forewings strongly suffused with blackish scales

ab. basisuffusa Lempke 1932

Females with the base of the forewings strongly suffused with blackish.

A multiple aberration of nigrofasciata Verity 1908 + magnipuncta Lempke 1933 + geisleri Bryk 1923

A very striking aberration.

nigrofasciata refers to the black streak from the black marginal band towards the discoidal spot.

magnipuncta is the enlarged discoidal spot, and geisleri refers to the discal spot extending into points towards the outer margin.

ab. faillae Stefanelli 1900

A male with the veins in the marginal bands strongly yellow on all wings.

ab. dentata Caruel 1955

The black marginal band of the hindwings shows on their inner side, in the interneural spaces, appearing as teeth directed towards the base. Resulting in a deep infiltration of the yellow veins into the bands

ab. pseudomas Cockerell 1889

This variation only occurs on the female, the spots in the marginal band are absent, or almost so on both wings

ab. pseudomas Cockerell 1889 + earinica Oberthur 1909

ab. pseudomas Only on the female, the spots in the marginal band are absent, or almost so on both wings.

ab. earinica refers to a female with the black forewing borders powdered with yellow at the apex.

ab. electra Lewin 1795

females with the spots in the hindwing margins absent.

ab. hyerensis Strand 1981

A very striking female example of this aberration.

The apex of the forewing is suffused with yellow on the black marginal band with the veins outlined in yellow.

On the hindwings the outer border is almost completely replaced with yellow, with only a small portion remaining near the top of the hindwing

ab. radiata Nitsche 1932

This female shows the yellow spots in the hindwing marginal band strongly radiated into streaks towards the outer margin.

ab. radiata Nitsche 1932

This female shows the yellow spots in the hindwing marginal band strongly radiated into streaks towards the outer margin.

ab. radiata Nitsche 1932

This female shows the yellow spots in the hindwing marginal band strongly radiated into streaks towards the outer margin.

ab. punctifera Braun 1923

Occurs only on the female. All that remains of the inner black marginal band on the hindwings are three black spots on the inner side of the yellow spots in the margin.

ab.parvipuncta Lempke 1954

The discoidal spot is quite reduced on the forewings only.

ab. magnipuncta Lempke 1933

The discoidal spot on the upperside of the forewings is very large.

ab. punctellata Braun 1930

In this aberration the discoidal spot is very small and tends to disappear as it is partly covered in orange scales

ab. cincta Le Charles 1926

On the upperside of of the hindwings the discoidal spot is surrounded by black.

ab. bipupillata Pionneau 1928

The hindwing discoidal spot is separated into two distinct spots on the upperside only, the underside discoidal spot remains normal. 

ab. duplex Cockerell 1889

These specimens have both forewings the helice colour. Hindwings are normal.

There are two specimens in the R.C.K. collection, with one hindwing normal and the other helice form. On further investigation these two were found to be well executed fakes.

ab. unimaculata Pionneau 1925

The discoidal spot on the upperside of the hindwings is single. The usual small spot above is absent.

NOTE:

There is a similar aberration for the underside of the hindwing, and this is called niediecki.

ab. niedeieki Strand 1909

On the underside there is only a single discoidal spot, the usual very small additional spot is missing 

ab. geisleri Bryk 1923

On the underside of the hindwing the discal spot is enlarged and drawn out into points towards the outer margin.

ab. rufomaculata Lempke 1938

The discoidal spot on the underside of the hindwings is dusted over the silver with carmine-red scales. The transitional forms are tinted a lighter red.

ab. seriata Rocci 1920

The underside of the forewings shows a complete series of strongly radiated marginal spots.

ab. semidemarginata Pionneau 1929

There is no sign of the antemarginal spots on the underside of the hindwings.

ab. semidemarginata Pionneau 1929

There is no sign of the antemarginal spots on the underside of the hindwings

ab. alba Lempke 1933

The ground colour of this female specimen is bordering on pure or dead white.

ab. aubuissomi Caradja 1893

The ground colour of these specimens is a yellowish-orange, and is intermediate between the type and helice forms. The hind wings are dark dusted with a large orange discoidal spot.

ab. flavomaculata Braun 1928

This a female helice form with the discoidal spot of the upperside hindwings light yellow instead of orange.

ab. nigra Aigner 1906

This is the  helice form of ab. pseudomas with the spots in the black band absent.

ab. nigra Aigner 1906

This is the  helice form of ab. pseudomas with the spots in the black band absent.

ab. nigra Aigner 1906 + ab. latemarginata Lempke 1933 + ab. basisuffusa Lempke 1932

ab. nigra  This is the helice form of ab. pseudomas that is with the spots in the outer margin of the forewings absent.

ab. latemarginata  Female with a wide marginal border, almost reaching the discoidal spot.

ab. basisuffusa  Female with the base of the forewings strongly suffused with blackish scales.

This is usually caused by a defective pupae.

ab. homoeotic

Any specimens showing a patch or patches of a portion of a wing transposed in a different place. This can happen on a y wing/s, and in some cases upperside scales can be deposited on the underside. or vice versa.
