Massive swarms of colorful butterflies that have descended upon the Karanji Lake have lent color to its environs especially the trees, shrubs and bushes, on which they perch. This is the first butterfly park in the state and after the development of the lake, the beautiful winged guests, fluttering from flower to flower all over the park; provide a glorious sight, interspersed with the chirping of birds.
Since more swarms of butterflies are expected to migrate from the lake after the monsoon gains momentum, Mysore Zoo envisages creating a conductive environment for the insects, by planting adult and larval food plants. The project to make Karanji Lake suitable for the butterflies was formulated by the Mysore Zoo during 1999, and work commenced during the same year. About 15 different species of butterflies were let free in the special park, where they bred and multiplied. During the first year, the park was not very popular with either among the migratory butterflies or the nature lovers of the region. Spread over one acre of land by the side of the lake, flowering plants carefully selected are grown to Attract butterflies. A wide variety of butterflies like Grey Pansy, Lemon Pansy, Peacock Pansy, Yellow Pansy, Tailed Jay, lue Mormon, Commo Mo mon, Crimson Rose, Common emigrant, Tawny coaster, Blue Tiger, Plain Tiger, Striped Tiger, Danid egg fly and many others can be seen dotting the park. Red Pierrot captivates the onlookers making it difficult for them to drag their eyes away from them.For sheer beauty, Blue pansy, Blue Mormon and Crimson Rose can be counted on. Butterflies fly during day time and rest with their wings held together, vertically above the back and hind wings over their fore wings except their lips. The Butterfly Park has added beauty to the lake which was opened to the public very recently.
