Abstract

The focus of this study is the surveying and confirming of the distribution of butterfly species around Mt. Kumjung in Busan. In fact, the ecosystem in Mt. Kumjung has been being ruined and the animals and plants are disappeared. Although we are trying to preserve them by use of "rest year" for the mountain, the species and numbers of insects in this area are still diminishing. In the field survey, I divided the mountain into four sections. The first section includes the mountain pass and the peripheral area(from Gym Park in the Children's Park to Kumjungbong). The second is the mountain pass from the north gate of Kumjungsanseong to Godangbong. The third is from Daecheoncheon Gym Park to Baekun Farm, and the fourth is from Hopo Saemaeul to the vicinity of the reservoir. From March to October on 2006, I had collected butterflies three times in month using an insect net and identified their population as follows. 11 Papilionidae, 8 Pieridae, 15 Lyeaenidae, 44 Nymphalidae, and 15 Hesperioidae were identified, in total 93 species. Dominance index(DI) for Papilio xuthus in Papilionidae family is 0.29, DI for Colias erate poliographus in Pieridae family is 0.22, DI for Celastrina argiolus in Lyeaenidae family is 0.27, DI for Polygonia c­aureum in Nymphalidae family is 0.09, DI for Daimio tethys in Hesperioidae family is 0.19 which shows the highest dominance. Biodiversity Index(H') is 16.47. Considered by altitude, 75 species were detected in the low altitude area(150m-250m, in the 3rd section, and the 4th section), 76 species were detected in the mid altitude area(250m-500m, in the first section), and 76 species were detected in the high altitude area(600m-800m, the 2nd section) indicating there is no prominent species difference by their residence by altitude.
