Current distribution of Nilgiri grass yellow Eurema nilgiriensis Yata (Lepidoptera: Pieridae), with an updated taxonomic key to Eurema of Western Ghats, India

Eurema nilgiriensis Yata, 1990, the Nilgiri grass yellow, was described from Nilgiris in southern India. There are not many published records of this species since its original description,and it was presumed to be a high-elevation endemic species restricted to its type locality. Based onthe external morphology (wing patterns) as well as the male genitalia, the first confirmed records of the species from Agasthyamalais and Kodagu in the southern Western Ghats, is provided here.

Diversity and abundance of butterflies of Kerala University Campus, Kariavattom Thiruvananthapuram

The present study reflects the richness and diversity of butterflies at Kariavattom Campus. This study reported 105 species of butterflies from four study sites. The highest number of butterflies was recorded belonging to the Nymphalidae (40 species), followed by Lycaenidae (23 species), Hesperiidae (18 species), Pieridae (13 species) and Papilionidae (11 species). This study revealed that Nymphalidae was most dominating family with a highest number of species and individuals.

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.
