The family Arctiidae is a large and diverse family of moths with around 11,000 species (Watson ＆ Goodger, 1986) in three subfamilies found all over the world, including 6,000 neotropical species (Scoble. MJ, 1995). The family is characterized in the following characters (Kitching ＆ Rawlins, 1999): hindwing with Sc+R and S fused for about 1/3 length of discal cell, occasionally completely fused, or only fused for 1/4 length of cell; almost always with either fore coxa, patagium, or abdomen orange or red and contrasting with color of dorsal thorax; metathorax with tymbal organs appearing as a striated band on katepisternum. Taxonomic study of the Arctiidae in Cambodia has been done by a few foreign entomologists. In the present study, we were collected three times from Cambodia in three protected forests are Seima, Central Cardamom, and North Cardamom (Pursat). Each times, we were collected from 3 to 5 sites in each forests. As the results of this study, about 70 species of 32 genera belonging to Arctiidae were recorded from Cambodia. The materials examined based on the collection of University of Incheon, which has collected from 2009-2010 in Cambodia by Cambodian and Korean researcher.
