Types of Butterflies
The first butterfly I learned to name was a monarch, mostly because my mother kept pointing at the orange ones in the garden. It took me years to notice the rest. Once you start looking, the variety is hard to ignore, and the names start to make sense.
There are around 17,500 butterfly species in the world, spread across six main families. Each family shares a few traits you can learn to spot. Size, wing shape, color, and even flight style all give you clues.
Below you will find the main types of butterflies, what sets each one apart, and where they live. The charts group them by family first, then by size, rarity, and region, so you can match a butterfly to its name in a few steps.

Types of butterflies and their names
Butterflies belong to the order Lepidoptera, which they share with moths. Scientists sort them into families based on wing structure, leg shape, and life cycle. Six families cover almost every butterfly you are likely to see in a garden, field, or forest.
The largest and most colorful tend to be swallowtails and brush-footed butterflies. Small flashes of blue or copper in a meadow are usually gossamer-winged butterflies. A fast brown blur near the grass is often a skipper. The table below sorts the six families by their main traits.
| Family | Scientific family | Size | Main colors | Distinctive feature | Examples |
| Swallowtails | Papilionidae | Large | Yellow, black, blue | Tail-like extensions on hindwings | Tiger swallowtail, birdwing |
| Brush-footed | Nymphalidae | Medium to large | Orange, brown, black | Reduced, brush-like front legs | Monarch, painted lady, peacock |
| Whites & sulphurs | Pieridae | Small to medium | White, yellow | Plain garden butterflies | Cabbage white, clouded sulphur |
| Gossamer-winged | Lycaenidae | Small | Blue, copper | Tiny, delicate wings | Common blue, American copper |
| Skippers | Hesperiidae | Small to medium | Brown, orange | Fast, darting flight | Fiery skipper, silver-spotted skipper |
| Metalmarks | Riodinidae | Small | Metallic orange/brown | Metallic spots on the wings | Jungle metalmarks |
Within those families sit thousands of species. The chart below lists common and notable butterflies, with the family each belongs to, its size and colors, and a feature that helps you tell it apart.
| Common type | Family | Size | Main colors | Distinct feature | Where found |
| Monarch | Nymphalidae | Medium–large | Orange & black | Long migration; toxic to predators | North America |

Largest butterfly species
Size is the easiest way to start grouping butterflies. The giants almost all come from the swallowtail and brush-footed families, and most of them live in the tropics. The record-holder is Queen Alexandra’s birdwing, found only in Papua New Guinea.
The table below ranks the largest butterflies by wingspan. The Atlas moth makes the list by size, though it remains a moth, not a butterfly.
| Species | Family | Wingspan | Where found |
| Queen Alexandra’s birdwing | Papilionidae | Up to ~25–28 cm | Papua New Guinea |
| Goliath birdwing | Papilionidae | Up to ~20 cm | New Guinea, Indonesia |
| Atlas moth* | Saturniidae (moth) | Up to ~24–30 cm | Southeast Asia |
| Owl butterfly | Nymphalidae | Up to ~16–20 cm | Central & South America |
| Giant swallowtail | Papilionidae | Up to ~14–18 cm | North America |
Smallest butterfly species
At the other end sit the gossamer-winged butterflies, the blues, coppers, and hairstreaks. Many are smaller than a coin. The western pygmy blue is one of the smallest in the world, with a wingspan near 1.2 to 2 cm.
Small butterflies are easy to miss, but they reward a close look. Their wings often carry fine spots, hair-like tails, or a metallic shine that only shows in good light. Slow down near low flowers and you will start to find them.
Rarest butterflies in the world
Rarity usually comes down to a small range or a fussy host plant. Queen Alexandra’s birdwing is rare because it lives in one corner of Papua New Guinea and depends on a single vine. The Palos Verdes blue, found near Los Angeles, was once thought extinct before a tiny colony turned up again.
The Karner blue is another example. Its caterpillars eat only wild lupine, so the butterfly vanishes wherever that plant disappears. Protecting these butterflies means protecting the exact plants and patches of land they need.
Common and popular butterfly species
Some butterflies turn up almost anywhere. The painted lady lives on nearly every continent and travels long distances each year. The cabbage white is the small white butterfly you see over vegetable beds, and the monarch is the famous orange traveler of North America.
In Europe and the UK, the peacock and the red admiral are the ones most people recognize. The peacock flashes the eye spots on its wings to scare off birds. The red admiral is bold and will sometimes land on your hand.
Toxic vs harmless butterflies
No butterfly can hurt a person. The “toxic” label only matters to the birds and lizards that try to eat them. A few species store poisons from the plants they ate as caterpillars, which makes them taste bad and keeps predators away.
This is where mimicry comes in. The viceroy looks almost exactly like the toxic monarch, so birds avoid both. Many harmless butterflies survive by copying a toxic neighbor. The table below compares a few well-known examples.
| Butterfly | Toxic or harmless? | How it protects itself |
| Monarch | Toxic to predators | Stores toxins from milkweed it eats as a caterpillar. Birds learn to avoid it. |
| Pipevine swallowtail | Toxic to predators | Takes up toxins from pipevine plants. Several other species copy its look. |
| Viceroy | Mildly distasteful | Looks like the monarch, so birds avoid both. The two share their defense. |
| Cabbage white | Harmless | No chemical defense. Relies on numbers and quick flight to survive. |
| Painted lady | Harmless | No toxins. Survives through wide range and constant movement. |
Endangered butterfly species
Butterfly numbers have fallen in many regions, and a few species now carry official protection. The migratory monarch was listed as Endangered on the IUCN Red List in 2021, then reassessed to Vulnerable in late 2023. In the United States, wildlife officials proposed listing the monarch as threatened in December 2024, though that listing was not yet final at the time of writing.
Other butterflies face the same pressures on a smaller scale. The table below shows the main protected species and what threatens each one. Habitat loss and pesticides drive most of the decline, so saving host plants is the clearest way to help.
| Species | Status | Region | Main threat |
| Migratory monarch | IUCN: Vulnerable | North America | Habitat loss, pesticides, climate change |
| Karner blue | U.S.: Endangered | Northern U.S. | Loss of wild lupine, its host plant |
| Apollo | CITES Appendix II | Europe, Central Asia | Climate change in mountain habitats |
| Palos Verdes blue | U.S.: Endangered | California | Urban development; one of the rarest |
Types of butterflies by region
Where you live shapes the butterflies you see. North America has its swallowtails, monarchs, and skippers. Europe and the UK have peacocks, red admirals, and blues. The tropics hold the showiest species, including the blue morpho and the glasswing.
The table below pairs each region with the butterflies you are most likely to meet there. Use it as a starting point for a local walk, then check a field chart to confirm what you find.
