本文以《迷蝶誌》、《蝶道》兩本散文集為觀察對象，探討吳明益「自然書寫」敘事策略。長期耕耘生態與自然書寫領域，吳明益不但是知名作家，也是學術能量豐富的大學教授，具有「意見領袖」特質。研究發現，兩書敘事脈絡一致，皆以「自然與蝶」為主題，以「科普與隱喻」為技術，並以「宏大敘事」為策略，帶領讀者造訪與追尋關於蝴蝶的故事，其中也兼及自身人文主義觀點的敘述。面對科普與人文的議題時，吳明益以其特有的慧見、修辭與極具說服力的文章鋪陳，帶領讀者造訪蝶舞翩翩的桃花源盛景。

In this research, “The Book of Lost Butterflies” and “The Dao of Butterflies” are employed as the observation objects to explore Mingyi Wu's “nature writing” narrative strategy. Mingyi Wu have been working in the fields of ecology and nature writing for a long time. He is not only a well-known author, but also a university professor with considerable academic authority and the characteristics of an “opinion leader.” The research found that both books have the same narrative thread, with “nature and butterflies” as the theme, “popular science and metaphor” as the technique, and “grand narrative” as the strategy, leading readers to visit and trace the story of butterflies, and also taking into account the narration of author's humanistic perspective. When addressing the issues of popular science and the humanities, Mingyi Wu employed unique insight, rhetoric, and persuasive elaboration to lead readers into the Peach Blossom Land with fluttering butterflies.
