Abstract

A total of 110 species and 433 individuals of butterflies belonging to five families and 16 subfamilies were recorded from seven forest types in Bako National Park. This study was carried out within two sampling periods, from 28th Aug -)'d Sept and 220d Nov -26th Nov 2006. The three-man-day samplings technique using standard butterfly net were conducted along selected c)(isting trails, fruit-baited traps were also applied as well in the adjacent area of the trails. Nymphal idae, represented by the highest species number and most abundant butterfly family in Bako National Park with 49 species and 235 individuals. Thi is followed by the Lycaenidae, PapiJionidae, Pieridae and Hesperiidae were represented by 36, 10, eight and seven speoie respectively, Chilades pandava pandava (Lycaenidae) appeared as the most abundant buttertly species in Bako National Park with 58 individuals captured. Ypfhima pandocus serforius, (Nymphalidae), represented by 36 individuals was the second most abundant species. Zeuxidia doubledayi horsjieldii was the most abundant species that captured by baited-trap throughout the sampling period. Prediction of butterflies' flight distance by using marked-recapture technique failed in this study as there was no butterfly recaptured. Among the seven forest types, beach forest has recorded the highest number species of butterfly, 54 species were sampled. Mixed dipterocarp forest and riverine forest have recorded 50 and 37 species, which was the second and third highest yield of butterfly. The remaining forest, namely heath forest, mangrove forest, open shrubland and cliff vegetation were represented by 25, 12, six and five species, respectively. Two species listed under CITES Appendix II, Troides helena mosyclus and T. amphrysus flavicollis were captured. Another two species, Graphium I!mpedovana empedovana and Charaxes durnfordi everffi listed under CITES Scheduled 5 as protected insects were captured. A pecies endemic to Borneo, Tanaecia orphne was captured with only a single individual and one species, Papilio iswara araspes which was claimed as rare species in Borneo were caught as well
