context_page_description: Troides amphrysus, the Malay birdwing, is a birdwing butterfly in the genus Troides in the family Papilionidae.
context_section_description: The egg is large and round and a pearly colour. Eggs are deposited on the food plant and the incubation period is two weeks.
  The first instar larva is black and bears numerous orange tubercles with short, black, branched spines. The intermediate instars 2, 3 and 4 are black. The thoracic segments have eight tubercles and the abdominal segments have six each. These are fleshy and lack spines. The dorsal tubercles of the 2nd, 3rd, 6th, and the 7th abdominal segments, are black. All the other tubercles are bright orange. In the penultimate and final instars the head is black and the thorax and abdomen is dark coffee brown. There is no saddle mark in this species. The tubercles are largely uniform in size, shape and of the ground colour. They are incline posteriorly and the apices are bent forwards to form small hooks. This species is not monophagous. The larvae feed on Aristolochia - A. acuminata and A. foveolata and on various Thottea species.
  The pupa is yellowish green and is marked with greyish veins as in a leaf. It has a broad dorsal saddle mark, this is lemon yellow transversely marked with brown streaks. The abdomen has three pairs of sharp dorsal processes, directed laterally. The pupal stage lasts from 27 to 30 days.
