Species Diversity and Faunaistic Characteristics of Butterflies in WuyunjieNational Nature Reserve,Hunan Province

2008～2010年,采用路线法对湖南省乌云界国家级自然保护区的蝶类物种多样性进行了为期近3年的调查,共记录蝴蝶147种,隶属于10科94属。蛱蝶科Nymphalidae Swainson,1827种类最多,弄蝶科Hesperiidae Latreille,1809的多样性指数最大。凤蝶属Papilio Linnaeus,1758对属多样性指数贡献值相对较大。记录国家保护种4种(宽尾凤蝶Agehana elwesi、中华虎凤蝶Luehdorfia chinensis、箭环蝶Stichophthalma howqua、大伞弄蝶Bibasis miraculata),其中中华虎凤蝶属于国家二级重点保护动物;湖南省新纪录种3种(金斑剑凤蝶Pazala alebion、报喜斑粉蝶Delias pasithoe和泰环蛱蝶Neptis thestias);宽边黄粉蝶Eurema hecabe采集数量最多(69头),是该保护区优势种群。蝶类昆虫区系主要以东洋成分为主,兼有古北和广布成分。
