This paper provides a list of moths captured in a region at latitudes 29–32°N and longitudes 127–130°E on the East China Sea on 14–28 June and 1–7 July 2005. Sixteen species of moths from the families Plutellidae, Crambidae, Sphingidae and Noctuidae were identified. Among these, three species were recorded on the East China Sea for the first time. The migration paths of the captured moths were analyzed using a three-dimensional backward trajectory analysis method. Predicted migration sources for these moths are Taiwan and Fujian, Guangdong, Jiangxi, Zhejiang, Jiangsu, and Anhui provinces in China.
