Research on diversity of butterflies of Phu Quoc National Park Kien Giang Province was carried out in November and December 2003. The park is located in the northern part of Phu Quoc Island. The research was conducted in different areas from the inhabitant areas to the natural forests without disturbance from sea water level to the highest peak of the Nui Chua 603 m . Butterflies were collected with insect nets. In addition the presence and their relative abundance of species were also recorded along transects at different habitats in order to assess the abundance of species. Butterfly transects with lengths ranging from 500 to 2 000 m were in habi- tats the natural forest the secondary forest the regenerating forest the shrub grass open and inhabitant areas the ridge and mountain tops. The total 139 species in 10 families were identified of which one species listed in CITES is Troides helena. The family Lycaenidae has the most species number 43 species . The next is Nymphalidae family 20 species Hesperi- idae 19 species Danaidae 18 species Papilionidae 11 species Pieridae 11 species Satyridae 10 species Riodinidae 4 species Amathusiidae 2 species and Acraeidae 1 species .
