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.
