The life process of Papilio Papilio

Egg stage-the egg is spherical. The top is slightly convex and peach-shaped;

The bottom is flat. The accessory gland secretion of the orange female butterfly adheres to the surface, with a diameter of about 2.5 mm and a height of about 2.2 mm.

Larval stage-each body has slender fleshy protrusions on the lateral glands, the lower line of the valve and the upper line of the thoracic throttle valve, and the tips of the protrusions are reddish. Larvae has a black head and a brown body, and its chest and abdomen are slightly lighter. The terminal larva is about 60~70 mm long, with black twill on the back and side of each segment, obvious white stripes on the 3rd and 4th abdominal segments, and white slender fleshy protrusions on the 7th abdominal segment. Natural enemies include wasps and bedbugs. Larvae has a smelly horn on its chest, which usually shrinks in the seam of its back plate. When it is frightened or disturbed, it can dig out and secrete unpleasant orange liquid to drive away the enemy.

Pupal stage-pupation, about 40~45 mm long, orange-brown, covered with white stripes. The ribbon is black and hangs on the fixture through the back of the chest. The middle chest and back are raised, with a pair of irregular flat protrusions on both sides, and flat leaflike protrusions on the back of the fourth to ninth abdominal segments. The mature larvae are near the host plant or between the hidden branches and leaves of the plant, looking for a suitable place to spin silk and pupate.

Adult stage-the male butterfly's front wings are blunt and round, and its back wings are long and narrow. The female butterfly is larger, with slightly wider front wings, slightly rounded rear wings and obviously wavy outer edges. The background color of the butterfly's front and rear wings is black, and there are large pink patches on the back. This species is a large butterfly with wings up to 10~ 13 cm. Spiders, lizards, frogs and birds are their natural enemies.
