The Common Bluebottle

Graphium sarpedon


Graphium sarpedon has a macular band that extends from the crest of the forewings to the inner margins of the hindwings on the sides of the upper and lower wings. The color of the ribbons varies from pale green, bluish green to dark blue. The hind wings have a series of blue submarginal spots on the upper side and additional red patches on the underside and near the base of the wings.

Larva: Graphium sarpedon larvae are pale yellowish brown upon hatching and turn dark greenish brown a few hours later to dark green at the last instar. This caterpillar has a pair of lateral spines each in the three thoracic segments, the other pair of white spines in the anal segment. Its body is covered in short dorsal-lateral turbanic rows with short setae.

Pupa: Pupa is green leaf-like veined with a slender and pointed thoracic angle.

Graphium sarpedon


Graphium sarpedon can be found in all forest habitats at an altitude of 0 – 1400 m asl, but mostly at low altitudes.


Continent : Asia

Country : Graphium sarpedon is the most widely distributed and common species among Oriental species. This species can be found in India, Sri Lanka, China, Japan, Malaysia, Indonesia (Kalimantan, Sumatra, Sulawesi, Java, Bali), Papua New Guinea, Australia and Solomon Islands.

Habits and Lifestyle

Graphium sarpedon is known for its agility and speed in flight. These species are often seen in groups, before mating they will circle around the flowering tree, after mating the male will look for mineral sources to replace minerals lost during mating. When eating, its wings are erect but keep shaking.

Diet and Nutrition

The diet of Graphium sarpedon larvae varies according to the location where they live. They eat the leaves of Beilschmiedia, Endiandra, Cryptocarya, Cinnamomum, Litsea, Neolitsea (Lauraceae), Annona, Melodorum (Annonaceae), Planchonella (Sapotaceae), and Doryphora (Atherospermataceae). When feeding, the caterpillars will rest on the top surface of the leaves, usually beside the midrib

Diet : Herbivore (larva), Nectarivore

Mating Habits

Graphium sarpedon reproduces by laying eggs (oviparous), the eggs are laid in leaf buds or in the petiole of the host plant. The eggs are round, cream-white in color, about 1.2 mm in diameter.

Life cycle (Metamorfosis) : Graphium sarpedon eggs take 3 days to hatch, after hatching the caterpillar will eat the entire egg shell as its first food. His body was initially pale yellowish brown but turned dark greenish brown a few hours later. It has a pair of lateral spines each of the three thoracic segments, and another pair of white spines in the anal segment. The body also has short dorsal-lateral rows of tubercles with long setae. After two days of eating young leaves, the first instar caterpillar grows to a length of about 5 mm. In the 2nd instar caterpillar, the basal tip of the thoracic spines turns black while the distal tip spines are still yellowish brown. Dark yellowish green body color with alternating yellow to dark green ventral segments. This caterpillar will continue to the next instar after 2 days and its body length reaches 6-8 mm. There is no drastic change in appearance in this 3rd instar caterpillar, takes 2 days to complete, body length is about 10-12mm. The body of this 4th instar caterpillar is mostly yellowish green, mottled with small yellow markings. On the back, a protruding transverse yellow band connects the two spines in the 3rd thoracic segment, a thin yellow band runs laterally on each side, the anus is bluish green. These instars last for 2 days with a body length of about 19-20mm. The 5th instar caterpillar is very similar to the 4th instar. The common Bluebottle caterpillar also has an osmeterium in the prothoracic segment. The 5th instar lasts 4 days, and the body length reaches 40-43mm. Towards the end of this instar, the length of the body gradually shortens, the color of the body almost completely turns green after the yellow band crosses and most of the yellow spots disappear. In the end, the caterpillar will settle on the leaf surface in an upright position and enter the prepupa phase. The pupa phase occurs a day later, the cocoon holds itself with a silk sash from the leaf surface. The pupa is green like veined leaves with a slender and pointed thoracic angle. The pupal period lasts 10 days, and the pupae turn black on the wing pads the night before eclosion. Adult butterflies appear the next morning.
