Diversity and Seasonal Abundance of Dragonflies and Damselflies in the Lake Cluster of Pokhara Valley, Nepal
Odonata (or odonates) are among the oldest and most well-studied insects worldwide; however, very few studies on this group have been conducted in Nepal. There was a lack of information on Odonata of Lake Cluster of Pokhara Valley (LCPV), one of the vital Ramsar sites in Nepal. Therefore, this study...

| description | Odonata (or odonates) are among the oldest and most well-studied insects worldwide; however, very few studies on this group have been conducted in Nepal. There was a lack of information on Odonata of Lake Cluster of Pokhara Valley (LCPV), one of the vital Ramsar sites in Nepal. Therefore, this study aimed to evaluate the diversity of Odonata and monthly variations in diversity in the three lakes (Maidi, Gunde, and Kamalpokhari) of LCPV. Odonates were sampled by the direct observation method along the transects laid on the existing trails around the lakes (three transects in each). A total of 27 species of Odonata from six families were documented. Of these, 15 were Anisoptera (dragonfly) and 12 were Zygoptera (damselfly). Species richness and abundance were the highest in Maidi and lowest in Kamalpokhari. However, there was no statistically significant difference in species richness and Shannon and Simpson’s diversities between the lakes, showing similarities in odonates’ community composition. Libellulidae and Coenagrionidae were the three lakes’ most diverse and abundant families. Shannon and Simpson’s diversities significantly differed between families in all lakes. September and November have the highest diversity and abundance. A significant difference in Odonata composition was found between the months. This research provides valuable insights into Odonata’s diversity at a Ramsar site in Nepal and underscores the potential for further ecological research and conservation efforts. |
