Objective To investigate the species, endemic species and floristic characteristics of flies in Pangquangou Nature Reserve in Shanxi Province. Methods Using entomological classification principles and methods. Results There were 142 species, 64 genera, 6 families of pet flies found in Pangquangou Nature Reserve in Shanxi Province. Among them, Muscidae, both in genus level and seed level, have great advantages, accounting for 32.81% and 49.30% of the known genera and species numbers of the reserve respectively. In the article, 34 species of broad species were recorded in the three kingdoms or above, accounting for 23.94% of the total number of species distributed in the nature reserve. There were 5 species widely distributed in the world, accounting for 3.52% of the species distributed in this reserve. Four endemic species, accounting for 2.82% of the species distributed in the reserve. Conclusion The floristic characteristics of the flies in Pangquangou Nature Reserve in Shanxi Province are dominated by the fauna in the Paleo-northern boundary.
