Biodiversity assessment of insects in the Chunchale–Belgaon Dhaga biodiversity zone of Nashik, Maharashtra

Insects are vital components of ecosystems, providing key services such as pollination, pest regulation, nutrient cycling, and food web stability. This study assessed insect diversity in the Shree Nasik Panchavati Panjrapole’s Chunchale–Belgaon Dhaga Biodiversity Zone, a certified organic reserve in Nashik, Maharashtra. Field surveys were conducted during December–January 2021–2022 using line transect and opportunistic sampling methods, with non-destructive photographic documentation. A total of 57 insect species were recorded, belonging to 33 families and 8 orders. Lepidoptera (28.07%), Odonata (15.79%), and Diptera (15.79%) were the most represented orders, while Nymphalidae was the dominant family (12.28%). The findings highlight the rich insect diversity supported by pesticide-free habitats and emphasize the importance of conserving such organic reserves as refuges for biodiversity. This study also establishes baseline data for future monitoring and contributes to ecological conservation efforts in the region.
