In the humid tropics, due to deforestation of primary forests, secondary forests and plantations are becoming increasingly widespread land-use systems in human dominated areas (A.D. Tiple et al., 2007). Despite their quick expansion and potential importance, the biodiversity conservation values of secondary and plantation forests remain poorly understood (B.U. Rani and A.S. Raju 2016), especially in relation to butterfly diversity. Along with the availability of larval and adult host plants, habitat quality appeared to be one of the most important parameters that is used to determine butterfly community structure (Kumar 2014). However, several studies (A.P. Singh et al., 2015) have discussed the potential of butterfly diversity in secondary forests, but diversity and species richness of butterflies across different secondary vegetation gradients were poorly understood. Among insects‚ butterflies are ideal subject for ecological studies of landscapes (P. Dey et al., 2017), and their value as indicators of biotope quality is being increasingly recognized because of their sensitivity to minor changes in micro-habitat, in particular, light levels (Kumar 2014). To a large extent, butterflies (being a pollinating agent) contribute to the growth, maintenance and expansion of flora in the tropical regions where these insects show high abundance and species diversity (A.V. Nair et al., 2014). The northeastern region of India is home to a rich diversity of butterflies and other insects, due to vegetative richness (K.S. Malabika and K.S. P 2009), and it is also globally recognized as one of 25 biodiversity hotspots (A.V. Nair et al., 2014).
