It's flight season is from April to June (Woodhouse noted that it has been captured between July and November in Kandy district). The larval host plants are Loxococcus rupicola[රන් දෝතළු]Calamus pseudotenuis[හීන් වේවැල්] (At the higher elevations) and Calamus radiatus[කුකුළු වැල්] (At the lower elevations). It probably feeds on leaves of other Calamus species.

Common animal distributed throughout the island, inhabiting rocky outcrops and/or trees in the country side and roofs of houses in urban areas. It is a purely nocturnal mammal and spends the day time curled up, asleep in its day time hideout usually a ceiling of a house in cities where rocky areas or tall trees are not readily available. It is mainly an arboreal animal and  feeds fruits and berries such as papaw, passion fruits, pineapple, kithul (Caryota urens) etc. But Common Palm Civet also eats rats, mice, frogs, birds, spiders, cockroaches as well as domestic chickens. It has a habit of depositing its droppings which often contain large quantities of undigested kithul and other hard-shelled seeds, on the top of large rocks and fallen tree trunks. It breeds throughout the year though more young are seen in the latter part of the year before the North-East monsoon. The young are brought forth in a hole in a tree, dry nook under overhanging rocks or often in a dry corner of a ceiling. Usually litter size is 3 or 4 in Sri Lanka. Except when a mother is accompanied by her broods it is usually seen singly.

Kyllinga polyphylla [Syn: Cyperus aromaticus]



An introduced weed native to the tropical Africa and Madagascar. According to the Flora of Ceylon Vol 5 it was only known from a place between Pussellawa and Ramboda at mile 28/10 along Kandy -Nuwaraeliya Rd (950 m a.s.l. ) in the Nuwaraeliya district. It is also noted that apparently it was a rather recent introduction. Since then (1985) it seems that it has become a widely distributed weed in paddy fields, marshes and roadsides, at least in the moist areas from lowland to the hill country (Personal observations).
