Arthropod diversity was considered as ecological indicators of sustainable agriculture and forest management. High-quality habitats have the relation with healthy ecosystem functioning. In this study, we collected the 101 species of arthropods which consists of 40 species of butterflies, 19 species of flies, 14 species of beetles, 10 species of grasshoppers, 7 species of wasps, 6 species of bugs, 3 species moths, 1 species of millipede and 1 species of centipede at la yaung taw, Naypyidaw union territory, Myanmar. Shannon-Wiener’s diversity indexes, Pielou’s Evenness Index (Equitability) and relative abundance in arthropods were analyzed. Arthropod’s diversity index was observed as 1.717 while the evenness index was 0.372. Importantly, relative abundance of butterflies is the highest as 39.6% among the arthropods. Thus, we suggest that Naypyidaw union territory possesses the sustainable agriculture of healthy ecosystem with high-quality habitats by the evidence of arthropod’s diversity index and butterflies assembling.
