The distribution of butterflies and dragonfliesis influenced by temperature, rainfall, altitude and the geology
of the land. Sri Lanka has traditionally been divided into five broad ecological zones–the arid zone, the low-country dry zone, the low-country wet zone and the central hill zone with a transitional intermediate zone between the lowlands and the hills. There are also tracts of grasslands which are of secondary origin in the hills that are home to some species of butterflies, though not exclusively. The mangroves and salt marshes are not specific to any species of butterfly but certainly offer excellent habits for some species.
