Abstract
I found a hitherto unknown mature larva of Papilionidae on Sassafras randaiense (Fig.8,4m in height) at Taipinshan (1,850m), Ilan Hsien, Taiwan on the 20th of August, 1966. The larva was found sitting on the upperside of a leaf of the tree 3m above the ground. It was 60mm in length, deep green in ground colour with unique dark brown markings (Figs,1,2). It became a prepupa (Figs.3,4) on the 23rd of August and pupated on next day. The pupa (Figs 5-7) was 35 mm in length and hibernated, After 255 days of pupal stage, unexpectedly a female of Agehana maraho SHIRAKI et SONAN emerged from the pupa on the 6th of May. 1967, Judging from the circumstances, the food-plant of this butterfly seems to be Sassafras randaiense.
