Odonates, or dragonflies and damselflies, are aquatic insects that have existed for over 250 million years. With over 500 known species in India, they help control pests like mosquitoes and protect crops by preying on gnats, midges, and mosquito larvae. They can best be observed near freshwater ponds and rivers during the monsoon season from May to November, especially around midday while wearing dull colored clothes.
