摘要
】百里峡风景区分布蝶类１１２种，隶属于９科６９属。其中，东洋界５０种，占总数的４４．６％，东洋古北界４６种，占４１．１％，表明其东洋界属性及由东洋界向古北界过渡的特性。蝶类分布型有２７个，单独归属某区的只占３．５７％，呈极明显分散现象，与邻近地区的共有种数均未超过５０％。百里峡的优势种是斑缘豆粉蝶，青豹蛱蝶，翠蓝眼蛱蝶，银纹尾蚬蝶，豆粒银线灰蝶。
An survey was carried out of the butterflies in the Bailixia (a gorge 100 li long) scenic area of Xuanhan county in 1992～1996. Altogether 112 butterfly species of 69 genera and 9 families were recorded. Fifty species were found to be of the Oriental group (accounting for 44.6% of the total )and 46 species were common to Palaearctic and Oriental groups (accounting for 41.1% of the total), suggesting that their fauna property should be primarily Oriental and represents a transition from Oriental to Palaearctic . Their distribution was shown to be highly dispersive . Of the 27 distributive patterns identified, only 3.57% was specific to a certain region. colias erate (Esper), Damora sagana ) (Doubleday), Junonia orithva (L.), Dodona eugenes Bates and Spindasis syama (Horsfield) are dominant, species in this area and are considered to be of exploitative importance.
