The Ceylon rose is a beautiful and extremely rare swallowtail butterfly found only in Sri Lanka. It is black and white in colour with pink spots (3). In both sexes, the black velvety abdomen is tipped with bright crimson. In males, the forewings are narrower than in females, and there is less white colouration. The pink and white marks on the hindwings are also smaller than in females (3).
This rare butterfly is endemic to Sri Lanka, where it is found in the south-west (4). The current strong-hold is the Sinharajah Forest Reserve and the hills around Balangoda and Morapitiya (3). There is much uncertainty as to the status of this species and there are no data on population trends (5).
Restricted to tropical evergreen rainforest at medium elevations (4) below 2000 feet (3). This species flies during the early morning or late afternoon when the sun is low. It takes nectar from flowers in clearings, along footpaths and beside roads. At other times of the day it remains within the forest and is rarely seen (3).
The Ceylon rose occurs in the Sinharaja Biosphere Reserve, and so receives a level of protection. Collecting specimens is strictly forbidden in the reserve, and is a punishable offence. The collection of this species for sale is banned in Sri Lanka. This butterfly was recently considered for listing on Appendix II of the Convention on Trade in Endangered Species (CITES) which would control international trade in the species. However, it was felt that international trade in the species is not a great problem, and that habitat management and protection should be the priority. Listing the species in Appendix II could even encourage trade, as it will draw attention to the rarity of the species and increase the price of specimens (5).
In arthropods (crustaceans, insects and arachnids) the abdomen is the hind region of the body, which is usually segmented to a degree (but not visibly in most spiders). In crustacea (e.g. crabs) some of the limbs attach to the abdomen; in insects the limbs are attached to the thorax (the part of the body nearest to the head) and not the abdomen. In vertebrates the abdomen is the part of the body that contains the internal organs (except the heart and lungs).
