The study was carried out from June 2021 to May 2022, to know the status and diversity of the Odonata (Dragonfly and Damselfly) fauna at Ecopark, West Bengal. They are essential for environmental monitoring and serve as biological indicators of the health of the ecosystem. During the study period, 34 species of odonates from 26 Genera and 5 Families were identified in the study area. Three families made up Suborder Anisoptera, while two families made up Suborder Zygoptera. Among them, 29 species of dragonflies belonged to the Aeshnidae, Gomphidae and Libellulidae families, while 11 species of damselflies belonged to the Coenagrionidae and Platycnemididae families. The family Libellulidae had the highest species composition (62%) followed by the family Coenagrionidae (29 %). Among all Odonates, 35% were very common (VC), 44% Common (C) 15% rare (R) and 6% were very rare (R) on the presence of their abundance. Such observation can provide insightful data on the status of Odonate populations in context to Rajarhat grassland
