Species composition and seasonal variation of butterflies in Dalma Wildlife Sanctuary, Jharkhand, India

Dalma Wildlife Sanctuary is located 10km from Jamshedpur in Jharkhand, India. The species composition and seasonal variation of butterflies was analyzed in this sanctuary over the course of 2 years. A total of 39 species belonging to 31 genera and 4 families were identified. Of these, Nymphalidae and Pieridae were found to be the dominant families, in comparison to Lycaenidae and Papilionidae. The monthly diversity was calculated by using the Shannon-Weiner diversity index. The highest diversity was found during late winter and spring while a comparatively low diversity was observed during the rainy season and summer. Nymphalidae showed the greatest variation with respect to distribution of species richness throughout the year. Nymphalidae and Lycaenidae showed greatest species richness and relative abundance during the rainy season. Little seasonal variation in species richness was observed in case of families Pieridae and Papilionidae
