About Noble’s Helen Butterfly:

  • The Noble’s Helen, closest to Papilio antonio from the Philippines and characterised by a large dorsal white spot, was once common in the montane forest at moderate elevations in northern Thailand.
  • This species of swallowtail butterfly has also been reported from the Myanmar, Yunnan and Hubei regions of China, Laos, Cambodia and Vietnam.
  • Butterflies are considered vital indicators of the state of biodiversity and key ecosystem functions.
  • Noble’s Helen with a wingspan of 100-120 mm was initially thought to be an aberration of Papilio Helenus, though the former has an extra white spot in the dorsum of the forewing.
