Abstract: Dragonflies and damselflies, in the ancient order odonata, are amongst the most attractive creatures on earth, first to have conquered the aerial domain. Yet we know little of their diversity in India and detailed ecology and habitat preferences of many species are poorly documented. Although much work have been carried out regarding the abundance and distribution of insect orders, no sufficient effort has been made to study the diversity and distribution of Odonates. Thus, in the present study an attempt has been taken to study the diversity and abundance of Odonates in West Bengal State University (WBSU) campus, West Bengal, India. A total of 32 species of Odonates were recorded from the study area from July to September, 2017. The family Libellulidae with 18 species was the most dominant among the Anisoptera (dragonflies) followed by Gomphidae (1sp.) and family Aeshnidae (1 sp.). Among the Zygoptera (damselflies), the 11 species recorded belong to the family Coenagrionidae and 1 species of family platycnemididae. As the area houses 32 species of Odonates including 20 species of Anisoptera and 12 species of Zygoptera, it can be presumed to have a good diversity which may be attributed to the grasslands, shrubs and small water bodies inside the campus.
