Online published on 4 January, 2018. Abstract Odonata diversity assessed in the rice fields of five major rice growing areas of Pattukkottai in Tamil Nadu viz., Agricultural Research Station (ARS) Farm, Pattukkottai, Anaikadu (ANA), Pokirikadu (POK), Ponnavarayankottai (PON) and Palanchur (PAL) revealed the occurrence of 19 species. These belong to 16 genera under 3 families viz., Libellulidae (12 species), Coenagrionidae (6 species) and Lestidae (1 species). Maximum Odonata abundance, species richness, diversity and evenness was found in the ARS and only 10–15% variation in species composition was found. Diplacodes trivialis (Rambur), Pantala flavescens (Fabricius), Orthetrum sabina (Drury), Crocothemis servilia (Drury), Trithemis pallidinervis (Kirby), Ischnura aurora (Brauer) and Agriocnemis pygmaea (Rambur) were the abundant ones.
