Troides cuneifera has been found once, almost 100 years ago, on the top of Khao Luang, highest mountain of Peninsular Thailand. Would be interesting search in this and other mountain tops of South Thailand to have a confirmation of this rare species.
This species is protected in Thailand, according to Ministerial Regulation No. 4, 1995, under the Wild Animal Preservation and Protection Act 1992, Article 6.
