Diagnosis
Medium-large-sized swallowtail butterflies. Wingspan 10-22 cm, sexually dimorphic in wing shape and wing colouration; forewing in male usually more elongate than female; ground colour black or tinged with yellow, white or whitish gray scales; hindwings usually undulate at margin, yellow without or with pearled sheen; forewing in female bearing more developed light-coloured scales along each of veins; hindwings of female broader than male and bearing more developed black dots on each cells.
Distribution
The whole genus comprises about 19-20 species, which widely ranges throughout the eastern part of Palaearctic Region, Oriental Region and the south Pacific area west to Wallace line.
Habitat and Ecology
The habitat types of this genus vary from tropical coastal forests to temperate cloud forests at about 3000 m. The adults usually soar in the sky, visit flowers or lick water along small creeks. The larvae of all species feeding on Aristolochia spp. and Pararistolochia spp.
Threats and Conservation Status
All species are protected by the CITES Appendix II and the European Union, and two of them, Troides aeacus formosanus and T. magellanus, are listed in the category II and I of the Wildlife Conservation Law of Taiwan, respectively. The major threats on this genus are deforestation and over-collecting. Some local populations are facing serious crisis by large-scaled forest cutting off. According to Parson (1996), Ornithoptera, Trogonoptera and Troides are the acclaimed flagship genera of international butterfly conservation, yet their needs have still to be seriously addressed. It is proposed that their long-term survival can be simply and practically enhanced by following a few key guidelines: notably through habitat conservation and enhancement of that habitat by management which would primarily include planting of Aristolochia and Pararistolochia larval foodplant vines. It is also cautioned, however, that such actions must not be postponed any longer. For more information about conservation of this genus see Igarashi & Fukuda (1997, 2000), New & Collins (1991) and Parsons (1983, 1996).
Remarks
The genus contains the following species. Among them, Troides dohertyi (Rippon, 1893) (Äu¤ó»n»ñ½º) has been downgraded to a subspecies of T. rhadamantus.
