Ornithoptera croesus, the Wallace's golden birdwing, is a species of birdwing butterfly found in northern Maluku in Indonesia.
It is a member of the Ornithoptera priamus species group which, including croesus, is only found east of the Wallace Line. The larval food plants are species of the genus Pararistolochia . Matsuka (2001) illustrates the early stages (from N. Maluku; see also Igarashi, 1979).
The "Wallace" in the common name, Wallace's golden birdwing, refers to Alfred Russel Wallace who described the species in 1859. Wallace recounts his capture of the butterfly in his book The Malay Archipelago (1869): "The beauty and brilliancy of this insect are indescribable, and none but a naturalist can understand the intense excitement I experienced when I at length captured it. On taking it out of my net and opening the glorious wings, my heart began to beat violently, the blood rushed to my head, and I felt much more like fainting than I have done when in apprehension of immediate death. I had a headache the rest of the day, so great was the excitement produced by what will appear to most people a very inadequate cause."
The specific epithet of Ornithoptera croesus, is named after Croesus, the king of Lydia from 560 to 547 BC.
Male: The upperside wings are black and have a yellow costal band. There is a clearly visible long oval sex brand (of androconial scales) in the black area. The underside is black marked with lines of green chevrons. The upperside hindwings are yellow and the underside is green, yellow towards the costa. The veins are black and there is a submarginal row of black spots. The head and thorax are brown and the abdomen is yellow.
Female: typical of birdwing butterflies, Ornithoptera croesus is strongly sexually dimorphic. Females are larger than males and have brown wings marked with lines of yellow chevrons.
Ornithoptera croesus was formerly considered vulnerable by the IUCN, but its status was changed to Near Threatened in 2018. [1] It is also listed in the Appendix II of CITES, restricting international trade to captive-raised specimens only.
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.
Ornithoptera is a genus of birdwing butterflies found in the northern portion of the Australasian realm, east of Weber's line; the Moluccas, New Guinea, the Solomon Islands, and northeastern Australia; except for Ornithoptera richmondia, which may be found in far northeastern New South Wales, Australia, therefore the southernmost distribution of birdwings. This genus includes the two largest butterfly species in the world, the Queen Alexandra's birdwing and the Goliath birdwing. Ornithoptera species are highly prized by insect collectors because they are rare, large, and considered exceptionally beautiful.
Ornithoptera alexandrae, the Queen Alexandra's birdwing, is the largest species of butterfly in the world, with females reaching wingspans slightly in excess of 25 cm to 28 cm. This birdwing is restricted to the forests of the Oro Province in eastern Papua New Guinea.
Ornithoptera goliath, the Goliath birdwing, is a birdwing butterfly found in New Guinea. It is the second largest butterfly in the world, after the Queen Alexandra's birdwing.
Trogonoptera brookiana, Rajah Brooke's birdwing, is a birdwing butterfly from the rainforests of the Thai-Malay Peninsula, Borneo, Natuna, Sumatra, and various small islands west of Sumatra. The butterfly was named by the naturalist Alfred Russel Wallace in 1855, after James Brooke, the Rajah of Sarawak. The larval host plants are Aristolochia acuminata and A. foveolata. Adults sip flower nectar from plants such as Bauhinia. Rajah Brooke's birdwing is a protected species, listed under Appendix II of CITES, meaning that international export is restricted to those who have been granted a permit. It is the national butterfly of Malaysia.
