Grass Demon (Udaspes folus)

An uncommon butterfly probably occurs all over the island excluding higher hills where its larval host plants available . Both Ormiston (Ormiston  W., 1924)  and Woodhouse (Woodhouse L.G.O. , 1950) treated it as a very rare insect in Sri Lanka. However now a days it seems to be not such a rarity, probably due to adopting of its larva to feeds on varies exotic plants such as Curcuma longa[කහ/Turmeric], Curcuma zedoaria [හරන් කහ], Hedychium coronarium [එළ මල්], Kaempferia galanga [හිඟුරු පියලි] and Zingiber officinale [ඉඟුරු/Ginger] (Jayasinghe H.D., 2014) some of them are widely cultivated. Curcuma oligantha is the only known larval food plant of it which is not introduced but indigenous (ibid).
