Abstract

Field survey was conducted to record thebutterfly diversity at different agri-horticultural ecosystems of Chamarajanagar district in Karnataka, India by following Visual Count Method (VCM) and Line Transect Method (LTM) during 2012-2013. Ninety five species belong to Nymphalidae, Lycaenidae, Pieridae, Hesperiidae and Papilionidae family members were distributed at various agri-horticultural ecosystems. The density, relative abundance, of butterfly species depended much on safe environmental conditions associated with floral abundance. Further, butterflies were grouped into very common (34), common (28), rare(24) and very rare (09) species found respectively 35.78, 29.47, 25.26 and 9.47%.Altogether, twelve different butterfly species Wildlife Protection Act, 1972. The Nymphalidae family members such as Dark Blue Tiger (Tirumala septentrionis), Blue Tiger (T. limniacea), Double Banded Crow (Euploea Sylvester) and Common Indian Crow (E. core) were migrants, well known for their long distance migration from east to west and vice versa. Since, Chamarajanagar district possess48% reserve forest area including B.R. Hills,M.M. Hills, Gopalswamy Betta and Cauvery Reserve Forest, where human interference is restricted. Perhaps, this might have influencedthe good growth of foraging and nest hostplants amidst Chamarajanagar district for the sebutterfly species.
