[Note Guidelines] Photographer's Note
The common birdwing is amongst the largest and most beautiful butterflies in Asia. The dramatic contrast of golden yellow hind-wings and glossy black forewings gives this species a striking appearance, and serves as a protection mechanism by warning potential predators that it is distasteful. The upper surface of the golden hind-wings features black boarders and veins, with females additionally possessing a row of large, triangular black spots. The colour of the male is brighter than that of the female, and the tip of the abdomen of the male is white. A prominent pink saddle distinguishes the caterpillar of this species, and the pupa has a leafy appearance that helps to camouflage it from predators.

Range: The common birdwing enjoys the widest distribution of all birdwings, stretching from India and Nepal in the west, to China in the north, and down through Southeast Asia to Indonesia in the south and east.

Biology: The female common birdwing lays single eggs, which she attaches to the surface of the Indian birthwort leaves. After hatching about four to five days later, the emerging caterpillar consumes the eggshell and then begins to eat the surrounding leaves, feeding both day and night.

After around three to four weeks the caterpillar begins its transformation into a pupa, which takes two days. The pupa remains in this state for the next two weeks as the metamorphosis into a butterfly progresses. After a total of 40 or more days from the moment the egg is laid, the adult common birdwing emerges from the pupa, allowing its wings to dry before attempting its first flight. The adult lives for around four to six weeks, feeding and mating before it dies.

Hi Pam

Another great macro shot from you!
The torn wings on this one really adda lot of drama to the compo here.
Other than that, the details are again razor-sharp and the colors are lovely. Terrific POV and DOF, too.

Bravo and TFS
