This study was conducted to investigate the change of moth communities by the effect of forest fire in Samcheok, Korea. Moths were collected 4 times a year from 2006 to 2009 with UV light traps at 3sites: Unburned area (Site 1), Surface fire area (Site 2), and Crown fire area (Site 3). A total of 3,804 individuals belonging to 727 species from 30 families were captured at the 3 sites. A total of 3,804 individuals belonging to 727 species from 30 families were captured at the 3 sites: 1,727 individuals of 505 species (27 families) at Site 1, 1,193 individuals of 353 species (24 families) at Site 2, 885 individuals of 340 species (25 families). The index of similarity (Index α) was higher between Site 2 and 3 in 2006, while higher between Site 1 and 2 in 2009. Moths were grouped into 16 categories by hosts of the larva stage. Based on our results, we discussed the change of moth communities by the effect of forest fire.
