臺灣蝶類紅皮書名錄

本報告根據國際自然保育聯盟威脅評估系統與準則(International Union for Conservation of Nature threat assessment system and criteria)，首次對臺灣464種蝶類進行國家蝶類紅皮書名錄評估。評估時排除了偶發種、疑問種、外來種、疑已滅絕物種，及離島物種(珠光裳鳳蝶除外)，最終納入358個種/亞種進行區域評估。結果顯示，臺灣共有27種國家級受脅蝶類，其中國家級極危(Nationally Critically Endangered)有2種，分別是黃鳳蝶和夸父璀灰蝶；國家級瀕危(Nationally Endangered)有5種，包括角翅黃蝶、臺灣脈弄蝶、南方燕藍灰蝶、大紫蛺蝶和波紋黛眼蝶；另有20種屬於國家級易危(Nationally Vulnerable)。其餘評估結果包括171種屬於國家級接近受脅(Nationally Near-threatened)、150種屬於國家級暫無危機(Nationally Least Concern)，以及11種屬於資料缺乏(Data Deficient)。在有進行評估的蝴蝶中，受脅物種占7.5%，接近受脅物種占47.8%；其中僅有6種被納入全球尺度之評估，全數被列為暫無危機(Least Concern)等級。

This report presents the first national Red List assessment of Taiwan's butterflies using the International Union for Conservation of Nature (IUCN) threat assessment system and criteria. Of the 464 butterfly species in Taiwan, 358 species/subspecies were selected for regional assessment, excluding vagrant species, questionable records, introduced species, presumably extinct species, and off-shore island species (except Troides magellanus sonani). The assessment identified 27 nationally threatened butterfly species in Taiwan. Of these, 2 species are categorized as Nationally Critically Endangered (NCR): Papilio machaon sylvina and Sibataniozephyrus kuafui. Five species are classified as Nationally Endangered (NEN): Eurema laeta punctissima, Praethoressa horishana, Everes lacturnus rileyi, Sasakia charonda formosana, and Lethe rohria daemoniaca. Additionally, 20 species are classified as Nationally Vulnerable (NVU). The remaining assessment results include 171 species classified as Nationally Near Threatened (NNT), 150 species classified as Nationally Least Concern (NLC), and 11 species classified as Data Deficient (DD). Of the species assessed, 7.5% was nationally threatened and 47.8% was nationally near-threatened. Among the evaluated butterflies, threatened species account for 7.5%, and near-threatened species account for 47.8%; among these, only 6 species have been included in global-scale assessments, all of which are listed as Least Concern (LC).
