This study endeavoured to conduct a comparative analysis of Odonate species, within discrete regions along the Meenachil and Pampa rivers, specifically in the Malarikkal and Parumala areas, throughout the period from March 1st to April 30th, 2023. The inquiry encompassed weekly visits to the designated study sites, where meticulous documentation of observations was conducted. A comprehensive analysis unveiled a total of 25 Odonate species in both regions. The Malarikkal region demonstrated heightened diversity with 18 dragonfly and 7 damselfly species, while the Parumala region exhibited comparatively diminished diversity, encompassing 7 dragonfly and 4 damselfly species. Regarding species diversity indices, Malarikkal exhibited values of 0.2022 for dragonflies and 0.25 for damselflies, indicating a moderately diverse Odonate community. Conversely, the Parumala region displayed lower diversity indices, with values of 0.0875 for dragonflies and 0.2857 for damselflies. These observations suggest discernible variations in Odonate species composition and diversity between the two regions. In summary, this study furnishes valuable insights into the Odonate fauna of the Meenachil and Pampa rivers, thereby contributing to the elucidation of regional biodiversity. The discerned distinctions in species composition and diversity underscore the imperative for targeted conservation initiatives in these aquatic ecosystems.
