Butterflies are one of the best on the botanical survey of Daniel & Nagar (2010) this taxonomically studied groups of insects (Robbins & Opler arboretum harbors 411 species of angiosperms, including 1997). New et al.

Outside of the monsoon season that tera are beneficial as pollinators, silk producers, indicators extends from mid-June to mid-September, the climate is of environmental quality, and appreciated for their aes- dry. The average rainfall of the region is 93 cm whereas thetic value (Pollard 1991; Kunte 2000; Kumar 2012). temperatures fall in the range of 12.5–40.1 °C (IMD 2014). The holometabolous life history of butterflies causes them to be exposed to a wide range of environmental influences, Field survey and data collection and they are highly sensitive to changes in temperature, humidity, and light levels (Erhardt 1985; Kremen 1992; Our survey was conducted in all seasons for an entire year Sparrow et al. 1994; Chey et al. 1997; Spitzer et al. 1997). from October 2012 to October 2013.
