Surveillance for subtropical moths through the inanimate pathway in the Korean Peninsula was investigated during the past seven years using the light trap in Baengnyeong and Daecheong islands, located near the Northern Limit Line (NLL) in the West Sea. Each record typically includes the taxonomic identify, its country of origin, and information related to inanimate pathway. A total of 2,201 individuals were detected, comprising 25 families, 441 species of Lepidoptera. The most dominant species was Chionarctia nivea (Noctuidae) with 44 individuals, followed by a crambid moth, Ostrinia furnacalis with 37 individuals. Among them, two species of subtropical moths, including Ischyja manlia Cramer and Spirama sp. belonging to the family Noctuidae, and they are mostly distributed in the subtropical area from the southern part of China to Borneo or Java. Interestingly, the other three species, Acronicta pruinosa (Guenée), Marumba spectabilis (Butler), and Spodoptera pecten Guenée were distributed in the southern regions, however, due to the effects of global warming, biotic province is now considered that may be certified moving northwards. Thus, it is very important to our weather conditions and further study on the surveillance of subtropical or/and southern species is needed, considering its possible status as a pest insect.

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.

Ten species of subtropical macro-moths including Squamura sp. of Metarbelidae, were discovered at Is. Daecheong in the West Sea. The other nine species are Zeuzera sp., Setora baibarana (Matsumura), Toccolosida rubriceps Walker, Hyposidra talaca (Walker), Celerena signata Warren, Creatonotos transiens (Walker), Vitessa suradeva Moore, Callambulyx rubricosa (Walker), and Dodusa nobilis Walker, and they are mostly distributed in the subtropical area from the southern part of China to Borneo or Java.
