Butterflies are comparatively easy to observe due to their large sizes and bright colors. Besides, since environments and plant resources are impressionable to the distribution of butterflies, they are usually considered as preferable bioindicator species. Moreover, while the biological classification and life cycle studies are complete in Taiwan, butterflies are also suitable for the environmental and ecological evaluations. In this study, based on the transect line method, Phoenix Logging Road and Bird Watching Trail of Xitou Nature Education Area, Taiwan National University are chosen for butterfly spices observation. The results show that butterflies in Xito Natural Educational Area can be classified into 98 species with 5 families, including 9 endemic species and 1 protected species. In these species, the Nymphalidae, which consists of totally 46 species, is the largest family, and Acraea issoria formosana is the most dominant specie due to its large amount. The results also show that, compared with the results in 1994, all families have changes: there are 21 new record species, and 34 species disappeared, including Abisara burnii etymander. Possible reasons include insufficient sampling or spice-time-caused changes.
