Butterflies have always attracted attention due to their unique colourations.  As most butterflies are highly specific in their niche utilisation, abundance of the species in a locality may advocate status of ecosystem functioning and environmental health.  In recent times, different anthropogenic activities and unscientific management of nature have resulted in a decline of butterfly communities at a rapid rate.  The objective of the present study is to study butterfly diversity in and around Midnapore Town, West Bengal, India.  A total of 82 butterfly species belonging to six families were recorded during the two years of the study period.  Of the six families Nymphalidae is the most abundant family comprising 42.54% of the total population followed by Lycaenidae (22.5%), Pieridae (19.03%), Papilionidae (8.58%), Hesperiidae (7.24%), and Riodinidae (0.11%).  Different diversity indices, Lorenz curve, Whittaker plot, and Gini index show high diversity in the butterfly community structure.  As Midnapore Town is the connecting area between the plains of Bengal and Chota Nagpur Plateau, the present study may be the baseline for further ecological, environmental, and conservation studies.
