Ceylon birdwing  (Troides darsius)

Chrysalis: Pupa of a butterfly.
Endemic: A species or taxonomic group that is only found in one particular country or geographic area.
Larvae: Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
Metamorphosis: An abrupt physical change from the larval to the adult form.
Pupate: The process of becoming a pupa, the stage of an insect's development, when huge changes occur that reorganise the larval form into the adult form. In butterflies the pupa is also called a chrysalis.
