Study on community diversity of butterfly in Xiaowutai mountain state nature reserves

To identify the species and compositions of butterflies in Xiaowutai Mountain State National Nature Reserve in Hebei,the community diversity of butterflies thereof was investigated in 4 different sites in 2010.Results show that there were 123 butterfly species belonging to 7 families and 75 genera.Nymphalidae had the most number of genera(25) and species(49),while Libytheidae only had 1 genus and 1 species.Nymphalidae and Satyridae had most dominant species,accounting for 78.57%,which constituted the main groups in butterfly community.Hesperiidae had the highest richness index(1.914 9) and evenness index(0.200 4).Nymphalidae had the highest diversity index(3.000 8).Papilionidae had the highest dominance index(0.866 9),while Papilionidae had the lowest richness index(0.552 6) and diversity index(0.552 6).The diversity index,specific richness,dominance index,evenness index and similarity coefficient of the four sites were calculated and analyzed.It is concluded that Yangjiaping had the most species(107),number of individuals(2 020) and highest diversity index(3.635 2).The similarity coefficient of butterfly community between Yangjiaping and Jinhekou was the highest.
