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.
