Abstract
Investigation was carried out on the diversity of butterfly fauna in selected localities of conservation and breeding
center of Arignar Anna Zoological Park (AAZP), Chennai, Tamil Nadu. A total of 56 species were recorded, 15 of
them belonged to Pieridae, 12 Nymphalidae, 9 Satyridae, 8 Papilionidae, 7 Danaidae, 3 Lycaenidae and 1 species
each belonged to the families Acraeidae and Hesperidae. Qualitatively and quantitatively Pieridae family were
comparatively dominant than that of other families. The notable addition to the 25 more species listed during this
observation were compared to previous field survey. Comparison of butterfly species distribution between the
different localities revealed that butterfly species richness was higher at mountain region with 52 species and lowest
of 25 species at public visiting areas. Visitor’s activities may be that reason for effects on butterfly distribution and lack
of vegetation. Each five endemic and protected species (i.e. endangered) listed under the Wildlife (Protection) Act
were highlighted greater conservation importances of the AAZP. It is suggest that butterfly species diversity
generally increase with increase in vegetation and declines with the increase in disturbance.
