The colourful damselflies and dragonflies of the order Odonata mostly seen together during monsoon season. Over all 18 odonates were recorded, represented by 16 genera and 3 families. We observed their presence during the onset of Northeast monsoon (late Sep 2014) and decline in their population during the onset of winter season (Dec 2014). From the month of september to december we encountered the maximum number of Odonates from the Pulicat lagoon. Orthetrum Sabina a migratory odonate species was the most dominant one contributed 19.6% followed by Brachthemis contaminate 11.3%, Ceriagrion coromandelianum 10.6%, Micrathyria tibialis 8.1% and least dominant species were Copera marginipes contributed only 0.38%. The presence of odonates is a mark of proof to conclude that the lagoon is still productive.
