The predominant types appeared to be the Oriental species, accounting for 62.1% of the total, followed by the wide-spread species, accounting for 23.3% of the total. The Palaearctic species were the least in number, accounting for 14.6% of the total. Cluster analysis in combination with consideration of the landscape , climate and vegetation of their distribution, the butterflies are zoogeographically divided into three regions.
