Abstract The Darwin wasp species Habronyx (Habronyx) pyretorus (Cameron, 1912), a solitary parasitoid of the giant silk moth Saturnia pyretorum Westwood, 1847, is recorded from Taiwan for the first time. The occurrence of this Darwin wasp species in Taiwan was initially revealed through online citizen science on social media, and all materials were subsequently reared from the mentioned host. As its host was artificially introduced from China to Taiwan, H. pyretorus is considered co-introduced with its host. In this study, H. pyretorus is redescribed based on Taiwanese specimens, and for the first time, its parasitism rate on wild populations of S. pyretorum, the duration before eclosion, and its adult lifespan are recorded.
摘要 本研究首次報告樟蠶軟姬蜂 (Habronyx (Habronyx) pyretorus (Cameron, 1912)) 於臺灣之分布記錄。本種為四黑目天蠶蛾 (Saturnia pyretorum Westwood, 1847) 的寄生蜂，其在臺灣的觀察記錄最初經由社群媒體上的公民科學家揭示，後續經由人工飼育寄主確認取得標本。由於其寄主係自中國引入臺灣，因此推測樟蠶軟姬蜂亦可能隨寄主一同引進。本文基於臺灣產標本重新描述樟蠶軟姬蜂，並首次記錄本種對四黑目天蠶蛾野外族群之寄生率、羽化前發育時間及成蟲壽命。
