Here is the butterfly tour and there are many more
Although geographically close to India, the zoology of the island displays many affinities with Indonesia and there is a marked degree of endemism, particularly in the remaining tracts of lowland forest to the south of the island. 242 species of butterfly have been identified, 42 of which are endemic to the island. As with the birds, the moist forests of the hill country and the south are home to some of the most interesting species but butterflies are a welcome sight throughout Sri Lanka and the aim of this short tour is to visit some of the very best areas to observe them and identify the species encountered.
