A total of 14 species and 05 families were recorded during the year 2022 to 2024. As previously recorded data, the total number of butterflies recorded from the Indian region is 1504 species according to Tiple, 2011 ^[10]. Butterflies represent the arthropods group which are the most beautiful and colourful arachnids or invertebrates on the earth and have essential aesthetic value as well it remains a matter of curiosity.

Butterflies fly thousands of miles during the winter season to different places like the warmer climates and return in the spring season conditionally. Butterflies always serve as the most important plant pollinators in our environment and pollinate more economically important plants (Borges et al., 2003). The studied area is the Hills of the Udayagiri which is situated near the city of theVidisha, which is located around the hills. The water reservoir and type of vegetation around the river Bais created an ideal habitat for the attraction of butterflies and many faunal species like insects, birds, fish, mammals, and so on. The eco-park of MPT is situated around the hills and makes the scenic beauty of the place.
