Abstract:
Background: Dragonflies and damsflies are one of the most diversified creatures on the earth. Materials and Methods: In the present study, Swanga-Vithoba lake was choosen to study Odonata diversity. This study was carried out in three seasons as: monsoon, winter and summer. Lake area was divided in four sites as: East, West, North and South. A total of 33 species representing 6 families were recorded from the multiple transect area of 1 km long and 5 m wide. Results: In summer, 88.89% indivuals were randomly distributed and 11.11% were aggregated, 89.65% were randomly distributed and 10.35% were aggregated in winter and 93.93% were randomly distributed and 6.06% were aggregated in monsoon. During monsoon, 650 flies were encountered which decreased to 424 individuals in winter and it was only 249 flies in summer. Brachythemis contaminata was the most abundant in monsoon. Lebellulidae was the dominant family with 19 species while other families were not as much diverse which could be due to their shorter life cycle and widespread distribution. Conclusion: Shannon diversity index indicated that winter is relatively diverse (1.357) followed by monsoon (1.342) and summer (1.319).
