With about 225 species, the Andaman & Nicobar Islands house some of the larger most spectacular butterflies of the world. Ten species are endemic to these Islands. Mount Harriet National Park is one of the richest areas of butterfly and moth diversity on these Islands.
Butterflies pick and choose the environment they would like to live in. They are equally particular about the plants they live on. Some like the Andaman Blue Nawab are so fastidious that they will feed on only one species of plant. In the event of non-availability if their chosen plant species, they would rather starve and die than choose an alternate.
