Cambodia covers an area of 181,035 sq km, among them, forests cover 53 percent, so there are abundant Insect diversities. Collecting expeditions of Insect were conducted several times from 2009 to 2010 (09. 7.2-7.11, 10.16-22, 12.25-12.30, 10. 4. 30-5.6) in Cambodia sponsored by Natioanl Biological Resources, Korea. Central Cadamon Protected Forest (N 11 41' 13" E 103 26' 31.3"), Seima Biodiversity Conservation Area (N 12° 08' 20.8", E 106 55' 2.7") and Prov. Pursat, Roveang (N 12° 19' 06.5", E 103° 3' 03.8") were main area surveyed by pitfall trap, light trap and sweeping, searching etc. Numerous individuals were collected and more than 150 species belonging to 40 families were founded, among them, there were lots of new and new recorded species. Among Cambodian insects, species of Lepidoptera, Coleoptra and Hymenoptera were preferentially introduced in here. The photos for species of dominant, rare, new and new recorded were provided, and also collecting sites and activities were presented.
