2008-2010年连续3年7-9月，对天祝夏玛林区的蝶类进行了研究。采集到蝶类标本2 000余号，经鉴定整理出蝶类71种及亚种，隶属8科50属。其中粉蝶科有9属20种，占总种数的28.2%，为优势类群；蛱蝶科有15属15种，占总种数的21.1%，眼蝶科13属14种，占总种数的19.7%，为次优势类群；绢蝶科1属9种，占总种数的12.7%；灰蝶科8属8种，占总种数的11.3%，为常见类群；弄蝶科2属2种，占总种数的2.8%，凤蝶科1属2种，占总种数的2.8%，蚬蝶科1属1种，占总种数的1.4%，为罕见类群。单种属有43个，占总属的86%，包含的种占总种数的61%；多种属有7个，占总属的14%，包含的种有28种，占总种数的39%；属种比值系数为0.86。结果表明，该地区蝶类以单种属为主。

The coenosis characteristics of butterfly species in the Xiama forest area of Tianzhu County

A field survey during July to September in 2008,2009 and 2010 was conducted to determine the coenosis characteristics of butterfly species in the Xiama forest area of Tianzhu County.2000 specimens were collected and were identified as 71 species/subspecies,which belonged to 8 families and 50 genera,in which Pieridae consisted of 20 species belonging to 9 genera,and accounted for 28.2% of total species,and was dominant species group;Nymphalidae consisted of 15 genera including 15 species with 21.2% of total species and Satyridae consisted of 13 genera including 14 species with 19.7% of total species and they were subdominant species groups;Parnassidae consisted of 1 genus including 9 species with of 12.7% of total species and Lycaenidae consisted of 8 genera including 8 species with 11.3% of total species,and they were common species groups;Hesperiidae consisted of 2 genera including 2 species,and Papilionidae consisted of 1 genus including 2 species,and Riodinidae consisted of 1 genus including 1 species,and they accounted for 2.8%,2.8% and 1.4% of total species,respectively,and were incidental groups.The monotypic genus was 43 and occupied by 86% of total genera,in which species was 61% of total species.The multiple genera were 7 and accounted for 14%,and species of which was 28 with 38% of total species.The ratio of genera and species was 0.86.This study suggested that butterflies in the study region were mainly monotypic genus.
