Fauna Investigation and Analysis of Butterflies in Wuyishan National Park in Fujian Province

This study investigated and analyzed the fauna of butterflies in Wuyishan National Park in Fujian Province, and aims to provide a scientific basis for the protection, exploitation and utilization of butterfly species diversity. A total of 565 adult butterfly specimens were collected in Wuyishan National Park from October 2018 to July 2022, and they were morphologically identified to 5 families, 71 genera, and 129 species. Among them, 3 genera (Cyllogenes, Cynitia and Hayashikeia) and 17 species were newly recorded from Wuyishan National Park, and 1 genus (Hayashikeia) and 7 species were newly record from Fujian Province. These new records make the known butterfly species increased to 5 families, 187 genera and 412 species for Wuyishan National Park, and 5 families, 232 genera and 615 species for Fujian Province. Among these butterflies collected, 5 species are in the "Species List of Terrestrial Wild Animals of Benefit or of Important Economic and Scientific Research Value under State Protection", and they are Troides aeacus, Burara miracula, Stichophthalma howqua, Stichophthalma neumogeni and Stichophthalma suffusa. Diversity index analysis at the family level shows that the species diversity of Nymphalidae is dominant. The more complex the habitat, the higher the butterfly diversity. The diversity in the habitat of evergreen broad-leaved forest is higher than that of the other habitats, and the butterfly diversity in the 800-900 m of altitude is higher than that of the other altitudes. Faunal analysis shows that the common species of Oriental and Palaearctic regions for the butterfly in Wuyishan National Park accounts for the majority (51.70%) in zoogeographic division of the world. For butterfly in Wuyishan National Park there are 47 distribution types in the zoogeographical division of China, among which the largest proportion (26.46%) belongs to Southwest-Central-South China distribution type, followed by the type of Southwest-Central-South-Qinghai-Tibet (10.19%) and the type of Southwest-Central-South-North China (9.95%).
