摘要

從2002年2月至2003年l月定期調查宜蘭縣礁溪鄉大礁溪實驗林場的蝴蝶生物多樣性，得知有鳳蝶科（Papilionidae）、粉蝶科（Pieridae）、蛺蝶科（Nymphalidae）及灰蝶科（Lycaenidae）等4科36種1,005隻蝴蝶分布。本報告除說明該地區的蝶類相外，並報導各科蝴蝶種數及隻數的每月變動情形，其中全年分布的蝶種只有琉球青斑蝶（Radena similes similes Linnaeus）。另一調查地點為宜蘭縣大同鄉棲蘭森林遊樂區，除比較不同年度7月至8月的調查結果外，並與大礁溪地區比較，得知棲蘭森林遊樂區的蝴蝶科數及種數皆較大礁溪地區多，且棲蘭森林遊樂區於1992年的蝶類相較2003年豐富。由此可知，大礁溪和棲蘭地區仍需經由栽植多樣性的蝴蝶幼蟲寄主植物和成蟲蜜源植物、避免遊客的人為破壞和干擾等措施來維持當地的蝴蝶生物多樣性。

From Feburary, 2002 to January, 2003, we monthly investigated the biodiversity of butterflies of the Dajiaosi Experimental Forest at Jiaosi Township in Yilan County. There were 1,005 individuals of 36 species and 4 families, Papilionidae, Pieridae, Nymphlidae, and Lycaenidae distributed in the forest. This paper not only states the butterfly fauna in this area, but also reports the fluctuation on butterfly species and numbers in each butterfly family monthly. The Radena similis similis is the only one species that can be seen all year round. In this research, investigating results of July and August of 1992 and 2003 from a different site, the Cilan Forest Recreation Area at Datong Township, in Yilan County are also reported and used to be compared with. The comparing results indicate that the family and species numbers of butterflies at Cilan Forest Recreation Area are both greater than those at Dajiaosi Experimental Forest. The abundance of butterfly fauna in 1992 was greater than that in 2003 at Cilan Forest Recreation Area. This implicates the requirement of efforts such as planting the larval host plants and adult's nectar plants, pre venting the artificial destruction and the interference of visitors to maintain the biodiversity of butterflies at Dajiaosi and Cilan Area.
