Butterflies are the most beautiful creature of the nature with magnificent colors. They play crucial role in maintaining ecosystem and as indicators of climate change. The purpose of this research was to examine the butterfly variety in the Sudurpaschim Province of the Kanchanpur district of the Bheemdatt municipality, from the month of April to November 2020. During this study, random observation method was used to locate different butterflies and those were captured on mobile phones. A total 52 species were recorded belonging to 5 families. Family Nymphalidae displayed highest species with 24 species and followed by families Lycaenidae with 10 species, Pieridae with 9 species, Papilionidae with 4 species and Hesperiidae with 5 species respectively. More exploratory work is required to estimate the population size and species abundance of the insects since the area is rich in flora, which offers a very appropriate environment and location for biodiversity. It is important to do systematic study, including diversity monitoring, also to prepare the checklist of butterflies along the elevational gradient in the Bheemdatt Municipality.
