中文摘要:金斑喙凤蝶Teinoplpus aureus Mell分布于亚洲东南部沿海地区,已报道有5个地理亚种。在世界保护协会(IUCN)2004年濒危物种红色名录中金斑喙凤蝶被列为DD(Data deficient)物种,在我国动物保护名录(1989)中在我国动物保护名录(1989)中被列为一级保护物种被列为一级保护物种。自从1923年以来,由于数据欠缺,尤其是生物学方面的数据,使得金斑喙凤蝶的研究工作一直难以深入开展,保护工作更是难以做到实处。作者于2003年3月至2005年11月在广西大瑶山开展了对金斑喙凤蝶(广西亚种)的自然形态学、生物学研究,通过野外实地观察、跟踪与记录等方法,结果首次揭示:在大瑶山金斑喙凤蝶1年发生2代,少数1年1代,以蛹越冬。成虫活动时间为每年的4月上旬至6月上旬和8月上旬至9月中旬,雌虫产卵方式为散产,通常为“一枝一叶一卵”式。已确认其寄主植物有两种:光叶拟单性木兰(Parakmeria nitida)与广东含笑(Michelia chapensis)。幼虫共5龄,老熟幼虫离开寄主植物,在林下层各类植物上化蛹。文章首次对金斑喙凤蝶物种在自然栖境中的形态学、生物学特征进行详尽描述。
英文摘要:The golden kaiserihind, Teinopalpus aureus, is distributed in the most southeastern and somewhat coastal regions near the East China Sea and the South China Sea in Asia, and five sub-species have been reported. It is a Data Deficient (DD) species in the 2004 Red List of Threatened Species of World Conservation Union (IUCN), and in China it is classified as the only category I species of butterfly under the Wild Animal Protection Law in 1989. After description in 1923 by Mell, there was no field studies on the butterfly for eighty years. During March 2003 to Nov. 2005, we studied the bionomics and morphology of the golden kaiserihind at Dayaoshan in Guangxi Province, China. Based upon the field observations, we recorded that it occurred two generations (partially one generation) annually, and overwintered as pupa. Adult occurred from the last ten-day period of April to the first ten-day period of June in the first generation, and from the first ten-day period of August to the middle ten days of September in the second generation. Female lays a single egg on leaf. Larvae have five instars.endangered butterfly, golden kaiserihind, Teinoplpus aureus, bionomics, morphology
