The study was carried out during the summer seasons from 2021 to 2022. Findings indicate that odonate species exhibit distinct habitat preferences closely linked to specific physicochemical water parameters. The presence of unpolluted aquatic habitats was observed to significantly enhance odonate diversity and persistence by reducing ecological disturbances. A total of 616 dragonfly specimens were collected across the study sites. These were identified as 21 species belonging to 12 genera and 4 families. The family Libellulidae was the most abundant, representing 75.16% of the collected specimens and comprising 15 species across 7 genera. This was followed by Gomphidae (15.25%, 3 species, 3 genera), Aeshnidae (9.41%, 2 species, 1 genus), and Corduliidae (0.16%, 1 species, 1 genus). Orthetrum coerulescens subsp. anceps (Schneider, 1845) was identified as the most abundant species, whereas Macromia moorei (Selys, 1874) was recorded as the rarest. http://www.iaees.org/publications/journals/arthropods/articles/2026-15(3)/dragonfly-fauna-as-bioindicator.pdf
