Objective：To faunal analyse and species diversity do of Calyptratae in the Wutai Mountain area.Methods：The investigation was conducted by insect taxonomy theory,biodiversity analysis and biogeography theory.Results：A total of 106 species,67genera and 7families of Calyptratae were found in the Wutai Mountain area,among which Muscidae 37 species 23genera,were predominant at both genus and species levels,accounted for 34.33%and 34.91%of all known Calyptratae genera and species in this area.From the world fauna,the characteristics of Calyptratae fauna composition in Palaearctic and Oriental and palaearctic were the main,accounted for 21.70% and 32.08% of all known Calyptratae species in Wutai Mountain area.From domestic fauna,wide distribution species which distributed in seven zoogeographic realms were the most,accounted for 21.70% of all known Calyptratae species in this area,the following were north China area＋northeast area and north China area＋northeast area＋mengxin area,accounted for 9.43% and8.49%respectively.Conclusion：Results showed that the Calyptratae in Wutai mountain area had the characteristics of species diversity and regional compatibility.
