Temporal diversity of urban butterflies: A case study in the campus of Ramakrishna mission Vivekananda centenary College, Rahara, West Bengal

Butterflies constitute key indicators that enable the monitoring of the impact of urbanization on plant and animal diversity. Present study focuses on the butterfly diversity and their seasonal variation in the campus of Ramakrishna Mission Vivekananda Centenary College (RKMVCC) Rahara, an urban area situated very close to Kolkata Metropolitan city. Present study suggested that RKMVCC campus is rich in butterfly diversity (57 species, 48 genera and 5 families) and harbors 43.18% of total known species from Kolkata. According to Wilson-Shmida beta index, the highest value was found between monsoon and winter (0.51) which indicates most contrasting species composition between these two seasons.
