Papilio demolion demolion

Cramer 1776 - The Banded Swallowtail

Koh Samui only.

A very swift flyer, found around the tops of trees, though it will come down to feed on Lantana or Ixias. As far as is known, this species has not been found 'puddling', unlike most other Papilionids.

This is not a common species on the Island, and can normally only be seen singly. Whilst, primarily a species of the forest, it does venture out into gardens to feed.

A unique habit of this species is to lay its eggs in a long string. When the larvae hatch, instead of eating the entire eggshell, as with most other members of this family, it only eats part, so keeping the string in place.
