I) Surveillance for subtropical-moths through the inanimate pathway in the Korean Peninsula was investigated during the period from 2006 to the present using the light trap in Is. Baekryeong-do and Is. Daecheong-do. A total of 438 species belonging to 27 families of Lepidoptera were identified. Among them, two species of subtropical -moths, including Ischyja manlia Cramer and Spirama sp. belong to the family Noctuidae were occurred at Is. Daecheong-do in the west coast. II) We are conducting an investigation into subtropical-moths detected from a vessel arrived in Yeosu sea port from this year. Among them, one species was identified into Histia flabellicornis Fabricius belong to the family Zygaenidae. These moths are mainly distributed in the subtropical area from the southern part of China to Indonesia. It is very likely that subtropical-moths have invaded in the Korean Peninsula through the inanimate pathway such as typhoons and/or vessels. To resolve this question, further researches should be done to determine the pathway by which these subtropical-moths occurred in Korea.
