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。
Butterflies were collected in every July-September during 2008 to 2010 with the methods of route survey and joint of line and dot in Tianzhu Xiaosanxia in Gansu,China.According to the identification of about 2 000 specimens of butterfly,77 species in 54 genera belonging to 8 families were obtained.Pieridae with 9 genera 22 species,28.5% of the total,was the dominant group.Nymphalidae with 17 genera 17 species,22.1% of the total species,and Satyridae with 13 genera 14 species,18.2% of the total species,were subdominant groups.Lycaenidae with 9 genera 9 species,11.7% of the total species,and Parnassiidae with 1 genera 8 species,10.4% of the total species,were common groups.Hesperiidae with 3 genera 3 species,3.9% of the total species,Papilionidae is 1 genera and 2species 2.6% of the total species,Riodinidae with 1 genera 2 species,2.6% of the total species,were incidental groups.According to the number of genera and species,45 were monotypic genu,accounting for 83.3% of the total genus.Among the 77 species,58 were Palearctic species,75.3% of the total species;13 were palearctic and oriental species,16.9% of the total species;6 were widespread species,7.8% of the total species;none was Oriental species.The result showed that butterfly fauna was mainly Palearctic specie in the area.
