abstract
Diversity of damselflies belongs to the insects order Odonata use as an ecological indicator for health of water resources. Ecological importance of these insects makes them valuable to examine the environmental impact of various kinds in the ecosystem. The present study was carried out to assess the diversity of damselflies around Jam Lake, Katol Taluka in the Nagpur district of Vidarbha (21°13`20.7"N 78°37`54.1" E). Observations were made through transverse lines along the edge of Lake and nearby areas. Diversity study for damselflies was carried out around the Jam Lake during the winter and rainy seasons from 2017 up to 2020 period. A checklist of 19 species of damselflies belonging to 11 genera (Agriocnemis, Aciagrion, Ceriagrion, Enallagma, Ischnura, Pseudagrion, RhodIschnura, Allocnemis, Copera, Disparoneura, Lestes) and 3 families (Coenagrionidae, Lestidae and Platycnemididae) were prominently identified. Total 52.63% are common, 5.26% are occasional and 42.10% are rare species were examined. Present study suggested that, species richness indicates the stable ecology and healthy water resources nearby the lake areas needs to be conserve with necessary protection measures.
