Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.6 in) of rain annually. Annual rainfall in the delta region is approximately 2,500 mm (98.4 in), while average annual rainfall in the Dry Zone, which is located in central Myanmar, is less than 1,000 mm (39.4 in). The average annual temperature is about 27℃(about 80℉). This expedition was conducted two times in two years (8.7~8.17, 2011; 2.2~2.9, 2012). As protected forest from government, these areas were almost natural conservation field. Pitfall trap, sweeping method, light trap and searching etc. were used to collect insect. As the result, totally about 30 families in Coleoptera was collected, among them Oodes species of Carabidae was highest number and species in Chrysomelidae, Cicindelodae, Scarabaeidae and Dynastidae etc., were collected. It was difficult to identification because of lack of references of this areas. Maybe lots of new or new recorded species will discover from Myanmar. Among Coleoptera species, with big sized beetles as the central figure, photos for species of dominant, rare, nominated species of new or new recorded were introduced, and also collecting sites and activities were presented.
