Abstract
This study aimed to record and analyze the diversity of odonates in the BJM College campus, a 14-hectare area located in Chavara, Kollam, India. The research was conducted in the area where individual sightings were recognized and documented using suitable field guides. Eighteen odonate species were recorded in the study area, comprising 10 dragonflies and 8 damselflies from 3 families. Amid this diversity, a greater number of families Libellulidae and Coenagrionidae were observed in the orders Anisoptera and Zygoptera, respectively. The species richness (R), Shannon-Wiener diversity (Hâ), evenness (E), and Simpsonâs diversity(1/D) values calculated were 3.34, 2.48, 0.98, and 10.90 respectively, while the two groups exhibit vertical niche segregation. The baseline data presented here serve as the foundation for evidence-based conservation suggestions.
