This page provides access to all named aberrations of a given species and Goodson & Read (1969) is a key resource in this regard.
Description to be completed.
Natural History Museum
britishbutterflyaberrations.co.uk
This section contains those aberrations that are considered new, and have yet to be formally defined.
britishbutterflyaberrations.co.uk (all aberrations)
On the upperside of the forewings the postmedian line is obliterated. The hindwings are similar.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The black bands in the discal and postdiscal areas on the upperside of the forewings are very much reduced.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the upperside of the forewings the black markings are reduced in the outer half.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside of the forewings almost without pattern, only some black spots in the basal area, a small black mark at the apex and a black spot at the inner angle. Hindwings with the basal area much darker than usual, the eye bands very broad but the eyes themselves not bordered. The margins of all wings are black.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
An obsolescence of the black of the upperside, hence an increase in the fulvous-brown ground colour.

= diniensis Wheeler.Butts.Switz.1903.p.85.
= impunctata Osthelder.Schmett.Sudbayern.1926.1.p.85.
On the upperside the red-brown marginal band of the hindwings is not ocellated.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The two lowest spots of the median band of the forewings are connected just above the inner margin in a short streak.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
An increase in the black markings of the upperside and consequent decrease in the fulvous-brown ground colour.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Very dark specimens in which the red-brown of the hindwings has almost disappeared. The figure shows a darkish dusting, the markings normal.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The hindwings on the upperside amply dusted with black. Presumably the forewings are normal.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The hindwings on the upperside show a transitory or complete formation of ocelli in the submarginal band. Reuss presumably means that the little black points of this band are enclosed in circles of blackish-brown to form eyes. Most specimens show a tendency towards this so the form is hardly worth separating [Goodson & Read].
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside of the forewings with an isolated black band in the discal area.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside with a strong increase in black pattern so that the ground colour is isolated into small spots. I cannot find any original reference to this form [Goodson & Read].
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The figure shows the forewings strongly suffused with blackish, only a chain of fulvous spots remain before the margin and three costal spots. The other normal markings can be faintly seen beneath the black dusting. Hindwings similarly blackish, with a chain of ocellated fulvous spots before the margin and clearly defined.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Forewings dark brown, with a very broad red-yellow transverse band at the margin, interrupted by the black-brown veins, very narrow at the costa and reaching its broadest point between the two cubital veins CU1 and CU2. All other red-yellow markings, with the exception of three very small red-brown spots in the discoidal area, fail completely. Upperside of hindwings normal. Fringes yellow-white. Similar but not identical with ab. horvathi Aigner. Differs completely from ab. horvathi by the normal hindwings.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside of the forewings all black except for two red costal spots and a submarginal chain of small reddish spots and three other small spots in the discal area in front of this chain. Hindwings with the basal half darker than usual, the rest normal. Similar melanic form to ab. cernyi Joukl.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside of the forewings with the whole patterning fused and all the black united into one large area in the median field, the base black, a few fulvous spots along the costa. Hindwings almost quite black but in the centre towards the costa some fulvous is visible. The eye band is narrow and there are broad black margins to all wings. On the underside the black pattern is very heavy.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the upperside the forewings are extensively dusted with green, the hindwings wholly so.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Upperside of the forewings white with a yellowish tinge, the hindwings fulvous.

= pallidior Oberthür.Lep.Comp.1909.3.p.234.
Upperside with the ground colour pallid but the markings strongly developed and encroaching on the pale areas. It bears some analogy to A. paphia [Argynnis paphia, Silver-washed Fritillary] ab. [form] valesina and A. aglaia [Argynnis aglaja, Dark Green Fritillary] ab. pallida, in all three there is an increase in the black markings simultaneously with a decrease in the depth of the ground colour. Oberthür’s ab. pallidior was from the French Alps but is almost certainly only an aberration.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with the cellular spots of the median band duplicated so that a double row of spots is formed. The black cellular spots in the margin are reduced and in their place remain only a few transverse streaks.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with only two black spots remaining of the chain of spots normally seen in the white median band. The description is that of the figure in Newman, presumably the third specimen on page 43. It is transitional to ab. expuncta Cabeau.

= unifasciata Caruel.Misc.Ent.1944.41.p.8.
Underside of the hindwings with the white median band showing no spots (pattern).
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with the black dots of the white median band thick or broad and forming an almost continuous line. The figure shows the spots replaced by short horizontal wedge-shaped streaks, from the costa down to the inner margin.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
The black pattern of the bands of the hindwings, especially on the underside, is increased.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of the hindwings all black markings are very broad, the two black wavy lines in the middle of the wing united into a band of large black spots. Underside of forewings with markings only at apex.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
On the underside of the hindwings in the discocellular white band there are thick black spots which are clearly separated. Transitional to ab. jubilaris Cabeau.
Natural History Museum
britishbutterflyaberrations.co.uk (all aberrations)
Underside of the hindwings with the red-yellow band, near the base, broken in many places. The figure is of the same form in M. didyma [Melitaea didyma, Spotted Fritillary] and shows this band reduced to separated spots of reddish-yellow. Skala says the aberration also occurs in cinxia so the name is valid.
