摘要
本研究主要針對北插天山臺灣水青岡林之夸父綠小灰蝶族群進行標識再捕法以估算族群密度，比較前人研究結果初步發現其族群量有減少之趨勢。其次，分布資料方面，首度確認逐鹿山為目前分布之最北界(121°25’42”E，24°49’59”N)及海拔最低(1360m)記錄，並分析本年度及過去所得之度冬卵資料，結果顯示母蝶在產卵位置上偏好枝條直徑小(<1cm)、距休眠芽近(<5cm)及背光的條件。另一方面，幼蟲耐餓能力的前測試當中，初步顯示幼蟲於5℃時具有耐餓一周的能力；最後，亦針對臺灣水青岡上鱗翅目資源性共棲者進行初步調查，結果顯示出水青岡林之鱗翅目多樣性頗高。
關鍵詞：夸父綠小灰蝶、臺灣水青岡、標識再捕法、資源性共棲者
Ecological studies on Sibataniozephyrus kuafui Hsu & Lin (Lepidoptera: Lycaenidae) (Ⅱ)
Abstract
The marked-released and recaptured method was performed to estimate the population size of Sibataniozephyrus kuafui Hsu & Lin in the forest of Fagus hayatae on Mt. Peichatienshan. Comparing with the previous study, a decline of population size of this rare butterfly was detected. Moreover, Mt. Zhulushan was confirmed to represent the northernmost distribution site (121°25’42”E，24°49’59”N) and lowest altitude (1,360m) thus far. Data analysis of the eggs appeared that the female butterflies prefer laying the eggs at the position near the dormant bud (distance<5cm) of small branch (diameter<1cm) in opposition to the direction of the sunlight. The pre-test of starvation-enduring ability showed that the larvae could endure starvation a week under 5℃. The preliminary investigation of the moths associated with Fagus hayatae revealed a high diversity of the lepidoptera funna. Keywords：Sibataniozephyrus kuafui Hsu & Lin, Fagus hayatae,
The marked-released and recaptured method.
