摘要
2008～2010年每年7～9月,在天祝小三峡采用以路线调查为主、点线结合的方法实施标本采集,共获得蝶类标本2 000多个,经整理鉴定出蝶类77种,隶属于8科54属.其中粉蝶科9属22种,占总种数的28.5％,为优势类群；蛱蝶科17属17种,占总种数的22.1％,眼蝶科13属14种,占总种数的18.2％,为次优势类群；灰蝶科9属9种,占总种数的11.7％,绢蝶科1属8种,占总种数的10.4％,为常见类群;弄蝶科3属3种,占总种数的3.9％,凤蝶科1属2种,占总种数的2.6％,蚬蝶科1属2种,占总种数的2.6％,为罕见类群.从属种数量来看,单属种较多,即有45属在天祝小三峡仅分布1种,占总属数的83.3％.在77种蝶类中,古北界种有58种,占总种数的75.3％；东洋界与古北界兼有种13种,占总种数的16.9％；广布种6种,占总种数的7.8％；东洋界种无分布.结果表明,该地区分布的蝶类区系成分以古北界的种类为主.
