玉山國家公園楠梓仙溪地區之蝶類相調查

中文摘要
楠梓仙溪保育研究站及其聯外道路-楠溪林道,位於玉山國家公園之西北園區境內,為塔塔加地區人為干擾少並具有豐富哺乳動物及植物資源之區域。楠溪保育研究站自106年起建構為科研基地供科學研究及環境教育用途使用,然而相較鄰近塔塔加遊憩區即有長期的蝶相調查資料,此區域之蝶相資訊仍十分缺乏。基礎生物相資訊之完備,有助於本區科研基地之發展。因此,本計畫於楠溪林道選定四條穿越樣線進行蝴蝶資源調查,並輔以腐果吊網陷阱進行蝶類相初探。自110年1月起至12月止,每月進行一次調查,結果共獲得390隻次共71種之蝶類。結合前人及本研究之調查成果,塔塔加地區之蝶類紀錄共計有164種,其中本次調查新增22新記錄種,包括以往多記錄於南部園區的截脈絹粉蝶 (Aporia gigantea cheni) 為首度於西北園區內記錄之蝶種,並為本種於臺灣本島最北之紀錄。此外,本研究亦發現兩蝶種之新紀錄寄主植物,分別為白漪波眼蝶 (Ypthima conjuncta yamanakai) 觀察其雌蝶產卵於禾本科 (Poaceae) 求米草 (Oplismenus undulatifolius) 之葉片上,以及廣食性之霓彩燕灰蝶 (Rapala nissa hirayamana) 幼蟲取食巒大越橘 (Vaccinium randaiense) 之花,為本種首次利用杜鵑花科 (Ericaceae) 植物之紀錄。蝴蝶多樣性以6至7月最高,結果與本區域之蜜源植物花期集中於春季及初夏相符。
英文摘要
Nantzuhsienchi conservation research station is located in the northwest region of Yushan national park. It is an area with fewer human activities but containing many mammals and diversified plant resources in this region. Since 2017, Nantzuhsienchi conservation research station has been constructed to serve as a scientific research base for the purposes of scientific research and environmental education. Therefore, the background knowledge of biota in this region is needed for the development of the above activities. Compared with the nearby Tataka recreation area, which have relatively long-term butterfly fauna investigation, the information of butterfly fauna in Nantzuhsienchi area is lacking, remaining to be explored. In this study, a survey including four line transects and four bait traps was set up in the Nantzuhsienchi forest road to investigate butterfly fauna in this area. From January to December, 2021, a total of 390 individuals of butterflies were recorded, and they were classified into 71 species in six families. Based on the results of previous investigations and this research, there are a total of 164 species of butterflies recorded in the Tataka area. The butterfly species richness and Shannon-Weiner index of the line transect survey peaked in June; the abundance peaked in July. This result is consistent with the flowering time of the main nectar plants in this area, concentrated in spring and early summer. Among 22 newly recorded species of butterflies in this study, Aporia gigantea cheni, whose records are mostly distributed in the southern region of Yushan national park in the past, now firstly recorded in the northwestern region, and this record is the orthernmost one in Taiwan. In addition, two new hostplants utilization records were also discovered in this study: (1) the hostplant of Ypthima conjuncta yamanakai was confirmed for the first time, ; a female was sighted laying eggs on Oplismenus undulatifolius (Poaceae) in October during the survey; (2) the caterpillar of Rapala nissa hirayamana fed on the flowers of Vaccinium randaiense, which is the first record of utilizing Ericaceae plant for this species.
