The green hairstreak is the UK's only green butterfly. Look out for the vibrant, metallic sheen of the undersides of its wings on grassland and moorland, and along woodland rides.

Purple hairstreak

Species

The Purple hairstreak is an elusive butterfly with a brilliant purple sheen. It is entirely reliant on oak trees and can be spotted chasing around the treetops in woodlands and parks.

Small copper

Species

The small copper lives up to its name in both colour and size! Look out for it from April onwards in dry, sunny habitats like heathland, downland and woodland. It can be spotted in gardens, too.

Brown argus

Species

The Brown argus favours open, chalk and limestone grasslands, but can also be spotted on coastal dunes, in woodland clearings and along disused railways.

Common blue

Species

The common blue butterfly lives up to its name - it's bright blue and found in all kinds of sunny, grassy habitats throughout the UK! Look out for it in your garden, too.

Holly blue

Species

Look out for the small Holly Blue in your garden or local park. It is the first blue butterfly to emerge in spring, and a second generation appears in summer. The caterpillars are fond of holly and ivy.

Large blue

Species

Despite its name, the large blue is a fairly small butterfly, but the largest of our blues. It was declared extinct in 1979, but reintroduced in the 1980s and now survives in southern England.

Black hairstreak

Species

The black hairstreak is a rare butterfly that is restricted to woodlands and hedgerows containing blackthorn - the foodplant of the caterpillar. It is both elusive and hard to tell apart from other hairstreaks.

Chalkhill blue

Species

Unsurprisingly, the chalkhill blue can be found on sunny, chalk grassland sites in southern England. Clouds of this beautiful blue butterfly may be seen fluttering around low-growing flowers.

Adonis blue

Species

The rare Adonis blue can be spotted on sunny chalk grasslands throughout summer. Males are a dazzling sky-blue in colour, while females are duller brown.

Small blue

Species

The small blue's name is a little misleading: it is our smallest butterfly, but only shows a dusting of blue on brown wings. It is scarce, occurring on chalk grassland, mostly in southern England.

Brown hairstreak

Species

The brown hairstreak is an elusive butterfly that spends much of its time in the treetops feeding on aphid honeydew.

White-letter hairstreak

Species

The white-letter hairstreak gets its name from the white lines that form a 'W' shape on its underside. It is an elusive butterfly, spending much of its time in the treetops.

Silver-studded blue

Species

The dazzling silver-studded blue is a rare butterfly of heathland habitats, mainly in southern England. It has undergone severe population declines in recent years.

Brush-Footed Butterflies

White admiral

Species

The White admiral is a striking black-and-white butterfly with a delicate flight that includes long glides. It prefers shady woodlands where it feeds on Bramble.

Purple emperor

Species

The male purple emperor is a stunning butterfly with a brilliant purple sheen. Look for it feeding around the treetops in woodlands, or on damp ground, animal droppings or even carrion in the morning.

Red admiral

Species

The red admiral is an unmistakable garden visitor. This black-and-red beauty may be seen feeding on flowers on warm days all year-round. Adults are mostly migrants, but some do hibernate here.

Small tortoiseshell

Species

The pretty small tortoiseshell is a familiar garden visitor that can be seen feeding on flowers all year-round during warm spells. Overwintering adults may find resting spots in sheds, garages or even houses.

Comma

Species

The comma has distinctively ragged wing edges, which help to camouflage it - at rest, it looks just like a dead leaf! It prefers woodland edges, but can be spotted feeding on fallen fruit in gardens.

Dark green fritillary

Species

The dark green fritillary is actually an orange butterfly with black spots. It gets its name from the dark green hue to the undersides of its hindwings. A strong flier, it can be seen on open, grassy habitats.

Silver-washed fritillary

Species

The silver-washed fritillary gets its name from the silver streaks on its underside. It is on the wing in summer, preferring sunny glades in woodlands. Despite declines, its range has spread over recent years.

Heath fritillary

Species

The rare heath fritillary was on the brink of extinction in the 1970s, but conservation action turned its fortunes around. It is still confined to a small number of sites in the south of England, however.

Small pearl-bordered fritillary

Species

The small pearl-bordered fritillary is a pretty orange-and-brown butterfly of damp grassland, moorland, and open woodland. It gets its name from the row of 'pearls' on the underside of its hindwings.

Speckled wood

Species

The speckled wood prefers the dappled sunlight of woodland rides and edges, hedgerows and even gardens. Despite declines, its range has spread over recent years.

Marbled white

Species

The striking black-and-white checks of the marbled white are unmistakeable. Watch out for it alighting on purple flowers, such as field scabious, on chalk and limestone grasslands and along woodland rides.

Grayling

Species

The grayling is one of our largest brown butterflies and a master of disguise - its cryptic colouring helps to camouflage it against bare earth and stones in its coastal habitats and on inland heathlands.

Gatekeeper

Species

The gatekeeper is on the wing in summer on grasslands, in woodlands and along hedgerows. Look out for the large, distinctive eyespot with two 'pupils' on each forewing.

Meadow brown

Species

One of our most common butterflies, the meadow brown can be spotted on grasslands, and in gardens and parks, often in large numbers. There are four subspecies of meadow brown.

Ringlet

Species

The ringlet gets its name from the small rings on the undersides of its wings. These rings show variation in the different forms of this species, even elongating into a teardrop shape.

Small heath

Species

The small heath is the smallest of our brown butterflies and has a fluttering flight. It favours heathlands, as its name suggests, as well as other sunny habitats.

Peacock

Species

The markings of the peacock are unmistakeable - big, blue 'eyes' just like a peacock's tail feathers. It can be seen feeding on flowers all year-round during warm spells, and overwinters as an adult.

Painted lady

Species

A well-travelled migrant, the painted lady arrives here every summer from Europe and Africa. This beautiful orange-and-black butterfly regularly visits gardens.

Dingy skipper
