The Shakambhari Hills in the Sikar region of Rajasthan host a rich and diverse entomofauna, yet have remained largely unexplored in terms of systematic entomological studies. This study presents a comprehensive inventory of insect species recorded from three distinct locations Kalakhet, Sakarai, and Bhagova by conducting random field surveys between 2021 and 2024. A total of 8,631 individuals belonging to 148 genera across 10 orders and 61 families were identified. Coleoptera was the most diverse and abundant order, followed by Lepidoptera and Hymenoptera. Presence of large number of insects from this region clearly indicates this region to comprise of tremendous diversity of insects and quite rich in flora which serve as host plants. These findings highlight the ecological significance of the Shakambhari Hills and underscore the need for conservation and further ecological research.
