Winged Wonders of Baidyabati

Nestled on the outskirts of Kolkata along the DVC (Damodar Valley Corporation) canal is a peri-urban conglomeration called Baidyabati. Currently an area under the Kolkata Metropolitan Development Authority, Baidyabati is paradise for both butterflies and birds. Although much of the areas comprise of agricultural lands, areas along the canal are dotted by trees and shrubs which act as host plants for the butterflies. Let us take a look at some of these winged wonders!

Common Silverline(Cigaritis vulcanus):

This species has a unique way to confuse its predators! In the first glance, it is difficult to figure out which is the head as it has hairy antennae protruding from the ends of the wings. It is a fast flyer but keeps to low bushes. Prefers open lightly wooded areas as well as gardens. Some of the larval food plants of the species in this area are Zizyphus rugosa, Lxora longifolia, Clerodendrum siphomanthus.
