摘要

蝶類因體型較大且顏色鮮豔，容易觀察且其分布容易受到環境與食草資源影響，是良好的環境生態指標物種，加上國內蝶類分類及生活史研究極為完整，適合作為環境生態評估之用。本研究選定溪頭鳳凰林道與賞鳥步道兩個步道，利用穿越線調查法調查步道中的蝶類相。調查結果共發現蝶類有5科98種，包含9種臺灣特有種及1種保育類。溪頭蝶類組成中以蛺蝶科46種為最多，數量上則以苧麻珍蝶(細蝶)為溪頭最優勢種；與1994年前人調查結果比較，各科組成均有變動，此次調查共有21種的新紀錄種，而有34種物種未見，包括白點褐蜆蝶(阿里山小灰蛺蝶)，推測原因為部份種類數量稀少，在調查中不易發現或是調查頻度不足，亦極有可能是蝴蝶組成經過時間或空間的變動有所不同。

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.
