During pre-monsoon, monsoon and post-monsoon a total of 68 species under 47 genera of six families; viz., Papilionoidea, Pieridae, Nymphalidae, Riodinidae, Lycaenidae and Hesperiidea were recorded. Of these family Nymphalidae accounted for 35% (24 species) of the total species count followed by Lycaenidae (17 species), Hesperiidae (10 species), Papilionoidea (8 species), Pieridae (8 species) and Riodinidae (1 species).
