Arctiinae are one of the most species-rich subfamily in the family Erebidae (or classified as family Arctiidae). Around 11.155 species of 750 genera have been described from all over the world (Heppner, 2005) of which 5.931 inhabit the Neotropics (Watson & Goodger, 1986; Heppner, 1991; Scoble, 1995). Taxonomic study of the Arctiinae in Cambodia has been done by a few foreign entomologists. As the results of this study, 182 species of 68 genera are reported on, of which described in recent pages 135 species of 44 genera are reported from Cambodia for the first time, five species are new to science (Bayarsaikhan & Bae, 2015; Bayarsaikhan et al., 2015; Bayarsaikhan & Bae, 2016): Danielithosia wooshini; Stictane cambodiensis; S. khmerensis; S. bokorensis; Cyana angkorensis. The materials for identification are based on the collection of Incheon National University, which were collected from 2009-2015 in Cambodia by Cambodian and Korean researchers.

The Sphingidae are a family of moths (Lepidoptera, Bombycoidae), commonly known as hawk moths. The hawk moths form a family of over 1500 species of small to very large moths (40-150mm) occurring on all continents except Antarctica. The most conspicuous aspect of sphingid biology is the capacity of the moths for fast, long distance, and often migratory flight. Sphingidae adult are appropriately shaped with narrow wings and a fusiform abdomen. Sphingidae is very popular group with both amateur and professional naturalists, but the taxonomic study of the Sphingidae in Cambodia has been done by a few foreign entomologists. In the present study, we were collected 12 times from Cambodia in 10 area for 6 province. As the results of this study, about 455 species of 289 genera of 18 families belong to Lepidoptera (NIBR, 2009-2014). Of which, about 60 species of 30 genera of family Sphingidae were identified from Cambodia. Most of them are recorded for the first time in Cambodia.

The family Arctiidae is a large and diverse family of moths with around 11,155 species of 750 genera (Heppner, 2005) in three subfamilies found all over the world, including 6,000 neotropical species (Scoble, 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. As the results of this study, about 90 species of 40 genera belonging to Arctiidae were recorded from Cambodia, most of them are recorded for the first time in Cambodia. Besides, 12 species have not been identified yet. The materials for identification are based on the collection of University of Incheon, which were collected from 2009-2012 in Cambodia by Cambodian and Korean researcher.

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.

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.
