Posting this picture after a long break here on treknature.
The Common Mormon (Papilio polytes) is a common species of swallowtail butterfly widely distributed across Asia. This butterfly is known for the mimicry displayed by the numerous forms of its females which mimic inedible Red-bodied Swallowtails, such as the Common Rose and the Crimson Rose.
The male has one morph only. It is a dark-coloured swallow-tailed butterfly. The upper forewing has a series of white spots decreasing in size towards the apex. The upper hindwing has a complete discal band of elongated white spots. It may or may not have marginal red crescents. The males are generally smaller in size than the females but not always. Both male and all forms of the female of P. polytes can vary considerably in size depending on climatic region.
The female of the Common Mormon is polymorphic. In South Asia, it has three forms or morphs. These are as follows:
This form is similar to the male, differing in that it always has strongly marked red crescents. It is the least common of the three forms. It is normally abundant where the Common Rose or Crimson Rose do not occur, such as in Himachal Pradesh around Shimla; although a few specimens of form romulus have also been caught alongside.
This female form of the Common Mormon mimics the Common Rose very closely. This is the commonest form wherever the Common Rose flies.
This female form mimics the Crimson Rose and is common over its range. It is not such a close mimic as the previous form being duller than its model, the Crimson Rose. It is easy to differentiate the mimics from models by the colour of their body—the models are red-bodied and the mimics are black-bodied.
Subhimalayan distribution. Male upperside dull, somewhat brownish black. Fore wing very sparingly irrorated with yellowish scales, that form ill-defined cellular and internervnlar streaks. Hind wing with a discal series of very diffuse greenish-white spots in interspaces 1 to 7 and an ill-defined tornal reddish lunule; the spots in interspaces 5 and 6 are the most diffuse, and beyond the whole series there is a postdiscal slight irroration of whitish scales. Underside: fore wing opaque dark brown, the internervular streaks broader, more prominent than on the upperside. Hindwing black; the discal series of elongate spots dingy white, larger and more clearly defiued than on the upperside, followed by a large tornal more or less vermilion-red spot with a black centre and a subterminal series of similarly-coloured lunules; the discal spot in interspace 2 bordered outwardly by an outwardly-curved lunule. Cilia black alternated with white. Antennae, head, thorax and abdomen black.

Hi Kapil,welcome back! And what a great return whit this beautiful pic,a great gift to the butterflies fans like me,a magnificent specie and excellent details and colors,i like it!! Have a nice evening and thanks,Luciano
Hello Kapil, An excellent return to TN. And why the long absence if you have such beautiful and interesting images to share? A real pleasure to view and an interesting accompanying note. Wonder why the female is polymorphous while the male is not and what prompts it. In mineralogy polymorphism is strictly controlled by temperature and pressure but other factors, perhaps equally determinative, must be at play here. Best wishes.
Hello Kapil! Nice to see a new photo from you!
Amazing scene and beautiful photo with wonderful colours and good sharpness.
Very well captured image with good sharpness and colour.
Nice to see that this Common Mormon is on its host plant'
Thank you for visiting my post.
