Moths were collected once a month from May to October each year during the period of 2013–2018. To reduce inter-site variations caused by weather or moonlight on moth catches in each trap, we sampled macromoths simultaneously at each of the six sites. Moth sampling was conducted from 7:30 p.m. to 12:30 a.m. local time. The moth samples were kept in a plastic container and transferred to the laboratory of Mokpo National University, where moth identification was made. A light bucket trap that included a 22 W ultraviolet light with a 12 V battery (BioQuip Co., USA) was used to collect insects at each survey site. Moths in the dataset included 14 Lepidopteran families: Bombycidae,  Drepanidae, Erebidae, Geometridae, Lasiocampidae, Limacodidae, Noctuidae, Nolidae, Notodontidae, Saturniidae, Sphingidae, Thyrididae, Uraniidae, and Zygaenidae.

This dataset can be effectively used to be a baseline for development of a network-oriented database to assess the temporal and spatial changes of macromoths in temperate and tropical forests.
