- subgenus: Aetheoptera
- Ornithoptera victoriae – Queen Victoria's Birdwing
- subgenus: Ornithoptera
- Ornithoptera aesacus – Obi Island Birdwing Twenty years ago this was (by far) the world's rarest birdwing species. Now commercially bred.
- Ornithoptera croesus – Wallace's Golden Birdwing
- Ornithoptera euphorion – Cairns Birdwing There is a spectacular and rare genetic mutation of this butterfly (less than 40 known examples, all from a single aberrant female) where the males are gold instead of green.
- Ornithoptera priamus – Common Green Birdwing, Cape York Birdwing, Priam's Birdwing, or Northern Birdwing Occurs as a number of subspecies, some of which are often regarded as full species e.g., O. (priamus) urvilleanus.
- Ornithoptera richmondia – Richmond Birdwing The smallest Ornithoptera species. Occasionally (and wrongly) regarded as a subspecies of O. priamus.
- subgenus: Schoenbergia
- Ornithoptera chimaera – Chimaera Birdwing
- Ornithoptera goliath – Goliath Birdwing A mosaic gynandromorphic specimen of this species sold by a Taiwanese dealer for US$28,000 in July 2006, which is possibly sets the world record for the highest price paid for a butterfly.
- Ornithoptera meridionalis – Southern Tailed Birdwing
- Ornithoptera paradisea – Paradise Birdwing
- Ornithoptera rothschildi – Rothschild's Birdwing
- Ornithoptera tithonus – Tithonus Birdwing
- subgenus: Straatmana
- Ornithoptera alexandrae – Queen Alexandra's Birdwing The world's largest butterfly. Listed on CITES Appendix I.
Two formerly recognized species of Ornithoptera are now regarded as hybrids:
- O. rothschildi x O. priamus poseidon – Originally described as species Ornithoptera akakeae. Known from a single female specimen.
- O. victoriae x O. priamus urvilleanus – Originally described as species Ornithoptera allotei. This butterfly is, because of its rarity, one of the World's most valuable, with male specimens typically selling for more than £4,000.00 (US$7,000.00). It would be an ideal candidate for commercial exploitation because its parents are not rare on Bougainville Island and can (apparently) be easily induced to mate with one another.
