Odonates play vital role in environmental monitoring and can be used as biological indicators of ecological health. The present investigation was undertaken as a pilot study to study the diversity and abundance of dragonflies and damselflies (Odonata) in Sarojini Naidu College campus, Kolkata, West Bengal, India. A combination of direct search and opportunistic sighting methods were applied to record 23 different Odonata species (18 dragonflies and 5 damselflies) from the study area during May, 2015 to April, 2016. In spite of the college campus being located in an industrial urban area, the present study revealed a striking diversity of Odonates. A suitable geographic location, favourable climatic conditions, appropriate vegetation provided a comfortable shelter for Odonata species to flourish in this area. This study is aimed towards contributing to the plan of biodiversity restoration in our campus and development of management strategies for conservation of this important group of insects.
