Diversity and Fauna Analysis of Butterfly Species in the Jiemuxi National Nature Reserve,Hunan Province
In order to understand the butterfly species diversity in the Jiemuxi National Nature Reserve in Hu-nan province,we conducted a systematic survey of butterfly species in 10 different habitats in Jiemuxi using the transect line method from 2022 to 2023,and analyzed the species diversity and fauna of butterflies in different habi-tats and groups.According to the survey results,a total of 127 butterfly species were recorded in the Jiemuxi Na-tional Nature Reserve,belonging to 5 families and 77 genera.Among them,the Nymphalidae was the most abun-dant(70 species,accounting for 55.12%),followed by the Lycaenidae(23 species,accounting for 18.11%).In addition,15 species of Hesperiidae(11.81%),11 species of Papilionidae(8.66%)and 8 species of Pieridae(6.30%)were recorded.There were differences in the butterfly diversity among different transect lines,with the Chenjiaxi and Yuan'erping lines having the highest diversity index(3.269)and the lowest diversity index(2.033),respectively.Among various butterfly groups,the diversity index was the highest in the Nymphalidae(2.838)and the lowest in the Papilionidae(1.579),the richness index was the highest in the Nymphalidae(10.170)and the lowest in the Pieridae(1.006),and the dominance index was the highest in the Pieridae(0.362)and the lowest in the Nymphalidae(0.256).The dominant species in each transect line varied with the habitat and vegetation.The dominant species in different transect lines and seasons were Pieris rapae Linnaeus,Ypthima perfecta Leech,Eure-ma hecabe Linnaeus,Pseudozizeeria maha Kollar,Talbotia nagana Moore,Zemeros flegyas Cramer,Papilio protenor Cramer,and others.Additionally,the Pieris rapae Linnaeus was the dominant species in the Jiemuxi Na-tional Nature Reserve.Results of the faunal analysis show that the butterfly species in the Jiemuxi National Nature Reserve were the most abundant in the Oriental species,with 75 species(59.06%),the Widely distributed species came in the second place,with 50 species(39.37%),and only 2 species(1.57%)were the Palaearctic species.The results of this study can provide basic information for the conservation and utilization of butterfly resources in the Jiemuxi National Nature Reserve,and also provide reference for the management of the reserve as well as the conservation and utilization of natural resources.
