摘要

Morphological description of immature stages and field observations of Sibataniozephyrus kuafui Hsu & Lin, 1994 from Taiwan are reported for the first time. Eggs and larvae were collected from Taiwan Beech, Fagus hayatae Palib. ex Hayata (Fagaceae). The larval stage is composed of four instars, and the entire larval, plus pupal stages took approximately 40 days in laboratory condition. The length of the life cycle in field is estimated approximately 280-330 days. Slight but consistent morphological differences are found between larvae and pupae of S. kuafui and the most closely species Japanses S. fujisanus (Matsumura, 1910) in coloration and size. Besides, the senior author found egg shells of S. kuafui from the specimens of Taiwan Beech deposited in herbarium, this discovery suggests the presence of this butterfly from other localities. Furthermore, brief description of habitat, hostplant and discussion on problems in conservation of this new species are also given.

本文首次描述臺灣產插天山綠小灰蝶Sibataniozephyrus kuafui Hsu & Lin, 1994之幼生期形態及成蟲之野外生態觀察。卵及幼蟲皆採自殼斗科之臺灣山毛櫸Fagus hayata Palib. ex Hayata。幼蟲期共有四齡，於實驗室中，自卵孵化至成蝶羽化約40天，並推測於野外之生活史約280-330天。插天山綠小灰蝶與其產於日本之最近緣種富士綠小灰蝶S. fujisanus之幼蟲及蛹在顏色和大小上具有細微之差異。而作者於國立臺灣大學植物學系植本館所藏，採自宜蘭縣三星山及桃園縣拉拉山之臺灣山毛櫸標本中發現插天山綠小灰蝶之卵殼，顯示本種蝶類至少曾分布於該區域。此外，本文並提供簡短之棲地觀察，寄主植物描述及本種於保育上之問題。
