臺大實驗林鳳凰自然教育園區之天蛾科（昆蟲綱：鱗翅目）調查

天蛾為中、大型蛾類，其成蟲的停棲方式、幼蟲的形態與行為，皆適合作為解說教育、推廣賞蛾的開端。本研究每月定期調查，建立天蛾種類於不同季節之多樣性變化及生態調查研究成果。2013年11月底至2014年10月之調查期間，以夜間水銀燈誘集及日間採集天蛾科昆蟲，共調查到20屬29種，61隻成蟲個體。一年調查結果顯示，天蛾各有39.3%於春天（3至5月）及42.6%於夏季（6至8月）活動，推測春、夏二季為天蛾科主要之發生季節。本研究調查期間，半緣缺角天蛾、平背天蛾、缺六點天蛾與白點天蛾出現的數量最多，且涵蓋二至三個季節，可能為鳳凰教育園區之優勢種。本文亦整理出調查到之天蛾種類幼蟲食草，其中外來植物與原生物種占的比重約略相等，且多屬於植群演替上較早期的陽性樹種或者林緣植物，少部分天蛾取食演替較為後期的植物。

Sphingids are a family of moth with moderate to large size. The behavior of its larvae and imago are suitable for education and also for promoting observation of moths. In this study, diversity changes of sphingids in different seasons were observed, and the ecological regular monthly survey has been done. During the studying period (November 2013 to October 2014), mercury lamps are used to attract Sphingids, which resulted in 20 genera and 29 species with a total of 61 individual found. After a year survey, 39.3 percent of sphingids are active in spring (March to May) and 42.6 percent in summer (June to August). Therefore, this study assumed that spring and summer are the major active seasons for sphingids. During this study period, Acosmeryx castanea, Cechenena minor, Marumba cristata and Parum colligate appeared the most, and the appearance of them covered two to three seasons, it could be identified as the major species of Feng-Huang Nature Education Area. Further, the check list of host plants of sphingids was also provided. For these plants, exotic species and native species accounted for roughly equal proportion. Mostly belong to positive species or forest edge plants on earlier succession of plant communities, and few moths feeding on late successional plants.
