Objective To study and grasp Ceratopogonidae （Diptera） of Shanxi Province, China. Methods Trapping with tent and person, luring with livestock and lamp, capturing with net were applied. Results There are 8 genera and a total of 30 species belonging to 3 subfamilies in Shanxi Province. There are 2 species of Leptoconops Skuse belonging to Subfamily Leptoconopinae, 2 species of Dasyhelea Kieffer belonging to Subfamily Dasyheleinae, 21 species of Culi- coides Latreille, 1 species of Forcipomyia Meigen, 1 species of Alluaudomyia Kieffer, 1 species of Palpomyia Meigen, 1 species of Mallochohelea Wirth and 1 species of Stilobezzia Kieffer belonging to Subfamily Ceratopogoninae. Among them, species of Culicoides Latreille are the most. They are mainly component parts of Ceratopogonidae （Diptera） in Shanxi Province. Ceratopogonid are almost in the activity of all day, but activity period of different kinds is also different. Cnlicoides is the main part of Ceratopogonid that the peak of activity is before sunrise and an after sundown. Leptoconops is the main part of Ceratopogonid that the peak of the activity is daytime. Conclusion Culicoides are mainly component parts of Ceratopogonidae （Diptera） in Shanxi Province, The species composing and preponderate population of Ceratopogonidae, activity period and habit are all different in each geography area. The study provides background data for Ceratopogorridae （Diptera） of Shanxi Province.
