තිත් මුවා[Thith Muwa]/Spotted deer(Axis axis)


Due to the lose of habitats and of extensive poaching, nowadays Spotted deer is confined to the protected national parks and forest reserves of the dry lowlands.  It lives as herds of few individuals to a hundred or more.  These herds mostly have single dominant male while some large herds may have several sexually matured stags. Only the males of spotted deer develop antlers and young stags shed antlers annually but later in life the shedding occurs irregularly.  They feed in grasslands in the morning and evening, resting during the heat of the day in the shade of trees.  Man, leopards and occasionally crocodiles and pythons are the enemies of the Spotted deer while jackal also kill fawns and injured animals.

කුළු හරකා/වල් මීමා[Kulu Haraka/ Wal meema]/Wild buffalo(Bubalus arnee)


It is believed that wild buffalos now inhabiting in the dry zone forests and grasslands are decedents of feral domestic stock that have gone wild with the abandonment of Anuradhapura and Polonnaru kingdoms, since no wild buffaloes are to be found in the south of central provinces of Indian mainland. Above theory further says that it was originally imported from plains of Ganges by ancient Sinhalese for the agricultural purposes. Buffalo of true wild state nowadays found only in remote dry zone areas such as Yala and Wilpattu national parks, while in other areas it easily mix and mate with feral populations. Herds seen in grasslands are compose entirely of cows, their carves and young bulls while old and sexually matured bulls lives solitarily in its own demarcated territory defending it from other intruder bulls.

Little Orange Tip (Coltis etrida limbata)

Rather rare butterfly inhabits coastal areas of north of Chilaw and Tangalla to Hambantota of extreme south. However sometimes it occurs further inland in north. Those from southern areas are larger, darker and very richly colored. Its only known larval food plant in Sri Lanka is Maerua arenaria of the family Capparaceae. W. Ormiston noted of a specimen taken at cart road at Haldummulla, at least 50 miles from its usual haunts and he believed that it had pupated on a Hambantota salt cart and hatched out on the way to Haputhale. Similarly he doubted of specimens of etrida race might brought over from India on the native boats because in Mannar district specimens that are very close to typical etrida  may be taken in company with typical limbata.
