The dragonflies were studied as indicators for healthy environment and good atmosphere based on the seasonal occurrence, abundance and flight activities aspects at National Kandawgyi Gardens (NKGs) from June 2008 to September 2011. The 30 species of dragonflies are distributed among three families. Dragonflies belonging to order Odonata are a well- known group of insects that are widely distributed all over the world and many people appreciate their striking colours and acrobatic flights. They are widely distributed in variable habitats such as ponds, lakes, streams, rivers and canals of all sizes. Since NKGs is diverse habitat, such as a lake, ponds, freshwater swamp, peat swamp, etc., different habitats are suitable for feeding, mating, perching and reproduction of many dragonfly species. The present research pursued to support the combination of conservation measures to ensure the continued survival of dragonflies and NKGs not only attracts human but a variety of living assets, including the dragonflies.
