Collection of watching dragonflies and damselflies



A fascinating hobby is gaining ground among naturalists around the world in recent times. It is all about watching dragonflies and damselflies. These insects are collectively called ‘Odonates' by scientists. So, like butterfly watching and birding, a new interest is catching up: odonate watching, or ‘oding'.

Peculiar lifestyles

Odonates lay their eggs in the water, damp soil and aquatic plants. The larvae live under water stalking aquatic prey, whereas the winged adults are skilled predators catching insects in the air. Dragonflies tend to prefer open areas as well as near water and perch with wings held open, whereas damselflies are frequently seen along streams sitting with wings held over their backs.
