The present study was carried out to fill the lacuna in the understanding of the diversity of odonates of Goa in general and dragonflies in particular on plateau and paddy fields in coastal villages—agricultural area at Velsao and Taleigao Plateau.  Diversity in plateau ecosystem was higher possibly due to a greater plant and insect diversity on the plateau, in comparison with the monoculture paddy agro-ecosystem.  Highest number of species recorded belonged to the family Libellulidae. Monthly diversity showed correlation with monthly average rainfall and humidity.
