Troides darsius (Gray, 1852) | |
Troides darsius, the Sri Lankan birdwing, is a species of birdwing butterfly found in Sri Lanka. It is the largest butterfly on the island and is also the national butterfly of Sri Lanka. [2] [3]
Among the largest and most gaudy of the Ceylon Lepidoptera is the great black and yellow butterfly (Ornithoptera darsius, Gray); the upper wings, of which measure six inches (15 cm) across, are of deep velvet black, the lower, ornamented by large particles of satiny yellow, through which the sunlight passes, and few insects can compare with it in beauty, as it hovers over the flowers of the heliotrope, which furnish the favourite food of the perfect fly, although the caterpillar feeds on the aristolochia and the betel leaf and suspends its chrysalis from its drooping tendrils. [4]
From Troides helena cerberus it differs as follows:
Male forewing: adnervular pale streaks not prominent on the upperside, more distinctly marked on the underside. Hindwing black, with a very broad discal slightly curved silky-yellow band or patch that extends beyond the cell from interspaces 2 to 7, and is composed of elongate outwardly emarginate yellow markings that are divided only by the black veins. In most specimens the inner margin of this band crosses the apex of the cell, but in many the cell is entirely black. Abdomen with some black markings beneath and a lateral row of black spots.
Female: Differs from cerberus female in the much greater extent of the black on the hindwing. Interspace 1 with a pale dusky-white patch in the middle; interspace 7 with an inner and an outer yellow spot; cell entirely black or nearly so, sometimes, but rarely, with the yellow extended into the apex.
Wingspan of 165–175 mm.
Cylindrical, dull purple brown, with two dorsal rows and anterior and lateral rows of fleshy tubercles, those on the eighth segment and a streak from its base to lower end of seventh segment being pale pink; between the tubercles are dark brown streaks. Feeds on Aristolochia (Moore.)
Pale purplish ochreous, bent backwards anteriorly; thorax conical, the top flattened and its sides angled; wing cases dilated and flattened laterally in the middle, their outer edge acute; two middle segments of abdomen with a dorsal pair of conical prominences. (Moore.)
The primary habitat is thinly wooded mountain forests from sea-level up to an elevation of 2,000 metres. Occasionally observed in gardens but generally rare in lowlands.
Troides darsius is threatened by deforestation.
Troides darsius is a member of the Troides haliphron species group. The members of this clade are:
Birdwings are butterflies in the swallowtail family, that belong to the genera Trogonoptera, Troides, and Ornithoptera. Most recent authorities recognise 36 species, however, this is debated, and some authorities include additional genera. Birdwings are named for their exceptional size, angular wings, and birdlike flight. They are found across tropical Asia, mainland and archipelagic Southeast Asia, and Australasia.
Troides minos, the southern birdwing, also called Sahyadri birdwing, is a large and striking swallowtail butterfly endemic to South India. With a wingspan of 140–190 mm, it is the second largest butterfly of India. It is listed as Least Concern in the IUCN Red List.
Belenois aurota, the pioneer or pioneer white or caper white, is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites, which is found in South Asia and Africa. In Africa, it is also known as the brown-veined white, and is well known during summer and autumn when large numbers migrate north-east over the interior.
Troides aeacus, the golden birdwing, is a large tropical butterfly belonging to the swallowtail family, Papilionidae.
Troides helena, the common birdwing, is a butterfly belonging to the family Papilionidae. It is often found in the wildlife trade due to its popularity with butterfly collectors. The butterfly has seventeen subspecies.
Papilio clytia, the common mime, is a swallowtail butterfly found in south and southeast Asia. The butterfly belongs to the subgenus Chilasa, the black-bodied swallowtails. It serves as an excellent example of a Batesian mimic among the Indian butterflies.

Hebomoia glaucippe, the great orange-tip, is a butterfly belonging to the family Pieridae, that is the yellows and whites. It is found in the Indomalayan realm and Wallacea.
Colotis amata, the small salmon Arab, is a small butterfly of the family Pieridae, that is, the yellows and whites. It is found in Africa and Asia. Adults are fond of smaller flowers for nectar and often fly low along the ground in search of wildflowers.

Cethosia cyane, the leopard lacewing, is a species of heliconiine butterfly found from India to southern China, and Indochina. Its range has expanded in the last few decades, and its arrival in the southern part of the Malay Peninsula, including Singapore, is relatively recent.
Tarucus theophrastus, the common tiger blue, pointed Pierrot or African Pierrot, is a small butterfly found in the Old World tropics. It belongs to the lycaenids or blues family.
Symbrenthia lilaea, the peninsular jester, is a species of nymphalid butterfly found in South Asia and Southeast Asia. It forms a superspecies with Symbrenthia hippoclus. There are numerous regional forms, and the taxonomy of the group is not well resolved.
Athyma nefte, the colour sergeant, is a species of brush-footed butterfly found in tropical South and Southeast Asia.
Doleschallia bisaltide, the autumn leaf, is a nymphalid butterfly found in South Asia, Southeast Asia, and Australasia. In Australia it is also known as the leafwing.
Ornithoptera paradisea, the paradise birdwing, is a species of birdwing butterfly found in New Guinea.
Troides vandepolli, the van de Poll's birdwing, is a montane birdwing butterfly occurring on Java and Sumatra. It is endemic for Indonesia and is protected by the Convention on International Trade in Endangered Species (CITES).
