Abstract

Two sites, one pond and a stream in Wayanad district, Kerala, India were monitored for a period of three months.The diversity of Odonata (dragonflies and damselflies) in the sites was studied using visual encounter surveys (VES). A total of 29 species of odonates from eight families were recorded during the study and the lentic system (pond) was more diverse in terms of odonate species. The pond ecosystem supports more generalist (eurytopic) species while the stream has many specialist (stenotopic) species.
