ADDITIONS TO LARVAL HOST PLANTS OF BUTTERFLIES OF THE WESTERN GHATS, KERALA, SOUTHERN INDIA (RHOPALOCERA, LEPIDOPTERA): PART 2

The study of butterflies is incomplete without the documentation of their larval host plants. The earlier works in this realm were by Bell (1909–1927), Wynter-Blyth (1957), and Sevastopulo (1973), who wrote on the host plants of Indian Lepidoptera (Kalesh and Prakash 2007). After a gap of many years, works by Kunte (2000, 2006), and Kalesh and Prakash (2007) are adding new information on site-specific host plants, which is of tremendous importance for the conservation of butterflies of the Western Ghats.
