With around 17,500 species of butterflies in the world, these colourful critters are important pollinators that help maintain the ecosystem.
They've adapted to live on every continent (except Antarctica) but generally prefer warm, open glades or woodland/forest. Butterflies are attracted to bright flowers and strong scents, and if you're looking to attract butterflies to your garden, our sister magazine, Gardeners' World, has put together this handy guide on how to make your garden butterfly friendly.
The UK has 59 species of butterfly, 57 of which are endemic, with the other two – the Painted Lady and the Clouded Yellow – being regular migrants. Unfortunately, you won't see any of the 10 largest species of butterfly here in the wild.
The largest species of butterfly we have in the UK is the rare swallowtail butterfly (papilio machaon britannicus), although it's currently restricted to the wetlands of the Norfolk Broads. This is thanks to its highly selective nature when it comes to egg-laying. Preferring to lay eggs only on milk parsley (peucedanum palustre) – the only food that Swallowtail caterpillars eat – much of the population has been in decline due to habitat loss, and the reduction in the land area where this moisture-loving milk parsley thrives. However, attempts are being made to re-establish the swallowtail butterfly elsewhere in the British countryside.

10. Miranda Birdwing
Wingspan: Up to 17cm
Distribution: Sumatra and Borneo
The first of several birdwing butterflies to make the top 10 largest, the Miranda Birdwing (troides miranda) primarily inhabits the tropical rainforests of Borneo and Sumatra.
= 8. Magellan Birdwing
Wingspan: Up to 18cm
Distribution: Philippines and Orchid Island, Taiwan
The Magellan Birdwing (troides magellanus) is a large, iridescent butterfly that has a blue-green sheen when seen from a different angle. This is thanks to its steeply set, multilayered rib-like scales that cause light to be diffracted.
= 8. Chimaera Birdwing
Wingspan: Up to 18cm
Distribution: New Guinea and Java, Indonesia
The Chimaera Birdwing (ornithoptera chimaera) is sexually dimorphic, with the female being brown in colour (the one pictured above is a male) and larger than the male. The Chimaera birdwing is a montane species (found on the slopes of mountains) and can be seen circling the tops of hibiscus and spathodea trees in the rainforests of New Guinea, Java and Indonesia.
= 6. Buru Opalescent Birdwing
Wingspan: Up to 19cm
Distribution: Buru, Indonesia
As the name suggests, the Buru Opalescent Birdwing (troides prattorum) is endemic to Buru, in the forests on the Maluku Islands of Indonesia. The species is classed as vulnerable, partly as a result of the logging occurring in their natural habitat.
= 6. Palawan Birdwing
Wingspan: Up to 19cm
Distribution: Palawan, Philippines
Also known as the Triangle Birdwing, the Palawan Birdwing (trogonoptera trojana) is endemic to the province of Palawan in the Philippines. Pictured here is the male; the female is browner in colour.
= 4. Wallace’s Golden Birdwing
Wingspan: Up to 20cm
Distribution: Maluku Islands, Indonesia
Wallace's Golden Birdwing (ornithoptera croesus) is found in northernMalukuinIndonesia, and was classified as near-threatened in 2018. It's a lowland species, preferring to inhabit swamps and other wet places.
= 4. Rippon’s Birdwing
Wingspan: Up to 20cm
Distribution: Moluccas and Sulawesi, Indonesia
First described in 1775 by entomologist Pieter Cramer, Rippon's Birdwing (troides hypolitus) is often likened to a wasp because of its yellow and black markings, this species of butterfly is endemic to the Moluccas and Sulawesi in Indonesia. Rippon's Birdwing is not significantly threatened, but it is protected.
3. Giant African Swallowtail
Wingspan: Up to 23cm
Distribution: West and Central Africa
The Giant African Swallowtail (papilio antimachus) can be seen flying above the rainforest canopy in western and central Africa, and on grassy hilltops during the breeding season. The Giant African Swallowtail is one of the most toxic species of butterfly, and has no known predators. If disturbed, it can spray a cloud of foul-smelling chemicals into the air. Although it was discovered in 1782, little is known about this species, and so far no one has been able to study the caterpillar or chrysalis stage; we don't even know what the caterpillar looks like.
2. Goliath Birdwing
Wingspan: Up to 28cm
Distribution: New Guinea, Indonesia
The second largest butterfly in the world is the Goliath Birdwing (ornithoptera goliath), which has a wingspan of up to 28cm. Like many butterfly species, the male is more colourful than the female, with the female Goliath Birdwing being browner in colour. As an aside, it may be that females have influenced butterfly colour diversity, by mating with the more colourful males.
1. Queen Alexandra’s Birdwing
Wingspan: Up to 31cm
Distribution: Papua New Guinea, Indonesia
