中文摘要： 本研究自八十七年六月至八十八年六月，研究太魯閣國家公園園區內之螢火蟲相並對棲地管理及螢火蟲相關解說活動提出方略及建議。園區內共有以下二十種螢火蟲之分布。分別為橙螢(Diaphanes citrinus Olivier)、蓬萊短角窗螢(D. formosus Olivier)、神木螢(D. sp.)（新種，將以D. nubilus 發表）、雲南扁螢 (Lamprigera yunnana (Fairmaire))、紅胸窗螢(Lychnuris formosana (Olivier))、大窗螢(L. praetexta (Olivier))、紅腹窗 螢( L. sanguiniventer (Olivier))、突胸窗螢(L. sp.)（新種，將以L. projecta發表）、赤腹櫛角螢(Vesta impressicollis Fairmaire)、黃脈翅螢(Curtos costipennis (Gorham))、黃肩脈翅螢(C. mundulus (Olivier))、中華熠螢 (Luciola chinensis (Linnaeus))、紋螢 (L. filiformis Olivier)、紅胸黑翅螢(L. kagiana Matsumura)、碧綠紋螢(L. sp. ) 、奧氏弩螢(Drilaster olivieri (Pic))、紅弩螢(D. purpureicollis (Pic))、高山弩螢(D. atricollis Nakane)、雙色垂鬚螢 (Stenocladius bicoloripes Pic)、慈恩雙櫛角螢(Cyphonocerus sp.) 等。神祕谷步道植被豐富，微環境溼涼，螢火 蟲種類共12種，佔全區種類數之百分之六十，但原住民自闢空地種植作物，為潛在之隱憂。區內以神祕谷步道及布洛灣為較佳之觀螢地點；唯神祕谷步道危險性較高，適宜成年大眾，布洛灣則不在此限。本研究並對園區內賞螢活動提出建議。 英文摘要： Field research was conducted during 1998. June to 1999 June for the firefly fauna of Taroko national park. 20 firefly species were recorded, they are: Diaphanes citrinus Olivier, D. formosus Olivier, D. sp., Lamprigera yunnana (Fairmaire))、 Lychnuris formosana (Olivier), L. praetexta (Olivier), L. sanguiniventer (Olivier), Lychnuris sp., Vesta impressicollis Fairmaire, Curtos costipennis Gorham), C. mundulus (Olivier), Luciola chinensis (Linnaeus), L. filiformis Olivier, L. kagiana Matsumura, Lucola sp., Drilaster olivieri (Pic), D. purpureicollis (Pic)), D. atricollis Nakane), Stenocladius bicoloripes Pic), and Cyphonocerus sp.. Among them, Curtos costipennis Curtos mundula, Cyphonocerus sp., Diaphanes citrinus, Luciola sp. and Lychnuris sanguiniventer are newly recorded from this region. 2 new species, Cyphonocerus sp. and Luciola sp. were recorded from Tsu-en and Bi-liu separately. Suggestions of firefly watching activities are made. Shakadangshi and Buluowan are highly recommended for the firefly watching sites.
