Udaipur : A rare species of butterfly has been reported after many years in Udaipur. Argynnis hyperbius or the Indian fritillary, is a butterfly of the Nymphalid or brush-footed butterfly family that were seen long back, claimed scholars researching on butterfly species in the region. A research scholar Neha Manohar spotted the colourful creature at Kewade ki Nal and clicked its pictures.
This species is mostly found in the Himalayas, in the outer ranges from Campbellpur in the Punjab to Sikkim, Oudh, Agra, Manbhum in Bengal, Assam, the Khasi Hills, Upper Burma extending to China. This variety is identical to the common leopard butterfly and black spots are seen on wings, however, a slighy shade of white differs the Indian fritillary from the common leopard specie, informed Mukesh Panwar, an expert on butterflies. These butterflies are only seen in old and dense forest and they feed on nectars of wild flowers. Years ago, it was believed that this variety used to lay eggs on viola plants but later with the decrease in numbers of the plant, these butterflies too vanished gradually.
