The study was carried out from the month of October 2021 to February 2022 in the Wildlife Sanctuary (27°31'30.89"N to95°22'0.53"E) and its nearby areas. A total of 63 species belonging to six families viz., Hesperidae, Nymphalidae, Pieridae, Papillionidae, Lyca-enidae, and Riodinidae were identified and recorded during the study. Among these families, Nymphalidae was the most diverse family comprising 38 species with an abundance of 1003 individuals. Approximately 60% of the species documented belong to the Nymphalidae family, highlighting the highest species richness. The dominant nature of the Nymphalidae family can be attributed to the polyphagous nature of the species under the family which enables them to thrive in diverse habitats.
