[Objective] The paper was to explore the species and dynamics of moths in Wujiatang wetland park in Dianchi lake.[Method] Moths under lamps in Wujiatang wetland park were investigated and studied regularly in 2016 and 2017, and the relationship among diversity index, indi-vidual number, species richness, evenness and diversity of moth community was analyzed.[Result] A total of 138 species of months belonging to 91 genera and 13 families were collected from Wujiatang wetland park, Dianchi lake, Kunming. The dominant insects were Crambidae and Noctuidae. The relationship between species and abundance relationship of moth community conformed to the niche priority occupation model, and the diversity index was not consistent with the evenness, but consistent with the species richness.[Conclusion]The study indicated that there were less species of moths in Wujiatang wetland park, and the community was unstable.
