摘要

本研究自2003年4月1日至9月30日共6個月期間，每月一次定期至宜蘭縣大同鄉棲蘭遊樂區調查蝴蝶種類及成蟲發生期。結果發現該地區有鳳蝶科（Papilionidae）、粉蝶科（Pieridae）、斑蝶科（Danaidae）、蛺蝶科（Nymphlidae）、蛇目蝶科（Satyridae）、環紋蝶科（Amathusiidae）、小灰蝶科（Lycaenidae）及挵蝶科（Hesperiidae）等8科48種蝴蝶，其中埔里三線蝶（Neptis taiwana Fruhstorfer）及大黑星挵蝶（Seseria formosana（Fruhstorfer））為臺灣特有種。調查期間蝶類種數有隨月份增加而增長，至7月份達最多有8 科34種，然後隨月份增加而降低的趨勢，但出現種類最少的為4月份之6科14種。各科蝴蝶種數以蛺蝶科14種最多，在48種蝴蝶中佔29.17%最少為環紋蝶科的1種，佔2.08%，具有相當高的蝴蝶物種多樣性。該地區各類蝴蝶的發生期以臺灣黃蝶（Eurema blanda arsakia（Fruhstorfer））、紫端斑蝶（Euploea mulciber barsine Fruhstorfer）、琉球青斑蝶（Ideopsis similes（Linnaeus））3種蝶類最長，在6個月調查期間皆觀察到，但於臺灣地區分布的小灰蛺蝶科（Riodinidae）與長鬚蝶科（Libytheidae）的蝴蝶，在棲蘭森林遊樂區卻一直未見到。由此可知棲蘭森林遊樂區仍保有多樣的蝴蝶資源，在調查期間皆出現1種以上的蝶種，為非常適合生態旅避的觀光景點，本結果亦可建立宜蘭地區的蝴蝶資源資料庫，提供日後臺灣生物資源監測的基本資料。

This study was investigated of butterfly species and adult occurrence period in 6 months at Cilan Forest Recreation Area, by monthly from April 1 to September 30 of 2003. There were 48 species in 8 families butterflies recorded in this area. The families were Papilionidae, Peridae, Danaidae, Nymphlidae, Satyridae, Amathusiidae, Lycaenidae, and Hesperiidae, respectively. The species Neptis taiwana Fruhstorfer and Seseria formosana (Fruhstorfer) are endemic to Taiwan. The increment of the buttertfly species were in accordance with the increase in month, the most appeared species had 8 families 34 species in July during the investigation, then the butterfly species reduced according to the month increased, but 14 species in 6 families at April that the least appeared species. The most number of butterfly species in families were 14 species in Nymphlidae, accounts for 29.17% in 48 butterfly species, and the less butterfly species in families was 1 species in Amathusiidae, accounts for 2.08% in butterfly species. There is relative high species diversity of butterflies in Cilan Forest Recreation Area. The adult occurrence period of butterflies in Eurema blanda arsakia (Fruhstorfer), Euploea mulciber barsine Fruhstorfer, and Ideopsis similes (Linnaeus) 3 species all can be found during 6 months investigation in Cilan Forest Recreation Area, but never be seen the species of Riodinidae or Libytheidae butterflies in this area. Therefore can know that there still had butterfly biodiversity resource in Cilan Forest Recreation Area. More than 1 butterfly species is recorded during investigation, in order to be very suitable for the sightseeing resort of the ecotourism. The results of this study can establish in the butterfly resource database of Ilan area, and offer the basic materials that the living resources of Taiwan will be monitored in the future.
