The Golden Birdwing Butterfly is mainly distributed in Fujian, Jiangxi, Guangxi, and Hainan provinces, and currently has only five subspecies. As a unique and precious species of China, it is known as the "National Butterfly" and the "Pride of Butterflies," and belongs to the world's rarest butterfly species.

Due to its rarity and preciousness, the Golden Birdwing Butterfly is China's only Class I protected butterfly, ranking first among the world's eight most precious butterflies. It is also known as the "Dream Butterfly" and a "living fossil of the world's animals." Its elegant posture, resembling a magnificent, noble, and radiant "lady," has earned it the title of "Queen of Butterflies." A single Golden Birdwing Butterfly once fetched a staggering million yuan at auction, demonstrating its exceptional rarity.
2. Two-tailed Brown Swallowtail Butterfly

The Two-tailed Brown Swallowtail (Papilionus spp.) belongs to the genus Papilionus in the family Papilionidae. It is a globally rare and precious butterfly. First discovered in western Yunnan, China in the 1930s, it is endemic to China, mainly distributed in Sichuan and Yunnan provinces, and is currently listed as a Class II protected animal in China.

First recorded in western Yunnan in the 1930s, it wasn't rediscovered until 1981 by mountaineers in Hokkaido, Japan, on Mount Gongga. The Two-tailed Brown Swallowtail is considered one of the most precious butterflies in the world.
3. Emperor Moth Yin-Yang Butterfly

The Emperor Moth is a butterfly species endemic to South America and is one of the rarest butterfly species, typically found only once in ten million butterflies. Its wings exhibit significant differences in shape, color, and size.

This butterfly possesses a pair of wings that are different in shape, asymmetrical, and distinct in sex; the left wing is female, and the right wing is male, thus exhibiting a mixed-sex characteristic. Due to the difference in the shape of these two wings, the Emperor Moth Yin-Yang Butterfly cannot fly, and its lifespan is only 6 days.

The Alexandrine Birdwing Butterfly is the largest butterfly in the world. It was first named by Rothschild in 1907 in honor of Queen Alexandra (1844-1925), wife of King Edward VII. This butterfly is found only in the Northern Province of eastern New Guinea.

Since 1989, the Alexandrine Birdwing Butterfly has been listed as an endangered species, and due to its scarcity, it commands extremely high value on the black market. This species is protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) as a Class I protected species, classifying it as an endangered species.

8. Morpho Butterfly

The Morpho heliotrope, also known as the Helena Morpho butterfly, is hailed as one of the most beautiful butterflies in the world.
