A faunal assessment of Munnar wildlife division, functioning under the Forests and Wildlife Department, has led to the discovery of two new species of butterflies in the State.
The four-day joint exercise by Forest officials and various NGOs in the past few days recorded 201 species of butterflies, 175 species of birds and 30 species of odonates (dragonflies and damselflies) across the national parks and wildlife sanctuaries in Munnar wildlife division. The highest numbers of species in each category were recorded from the Chinnar wildlife sanctuary.
The survey detected two new butterfly species in the State, viz., Jewel fourring and Silver forget-me-not, from Chinnar, both of which have been added to the Kerala checklist. The Southern birdwing and the Grass jewel, the largest and smallest butterflies in the country respectively, were also recorded. Other species that were detected were the Western Ghats endemics like Red-disc bushbrown, Palni bushbrown, Palni four ring, Palni fritillary, Nilgiri clouded yellow, Nilgiri tiger and Palni sailor.
