It's a mixed picture for our nation's butterflies – some are sadly in decline, while others are on the up or expanding their territory. They all need our help regardless, and gardeners can play a key role in supporting these beautiful creatures.

It's not difficult to lend a hand – just plant a range of nectar-rich blooms for butterflies to feed on throughout the season, and if possible, caterpillar food plants.

The recent success of some species shows that the fate of certain butterflies can be turned around, and that, despite bad weather, climate change and loss of habitat, some species, such as the comma and holly blue, are faring well.

Here are some butterflies that you may see in your garden, with advice on the food plants they breed on and feed on.


Peacock (Aglais io)

Hibernating wildlife - peacock butterfly

Large and striking, this butterfly has peacock-like eyespots on its wings. Look out for it between mid-March and mid-May, then mid-July until hibernation time in September. The peacock butterfly is becoming more common. It's a familiar sight in the southern half of Britain, but is a relative newcomer in the north. It's now colonising Scotland.

Caterpillar food plants: common nettle
Butterfly food plants: buddleja, sedum

The small copper butterfly is widespread across the UK, except northern Scotland. Numbers are down 37 per cent in the last 40 years, likely due to climate change.

Caterpillar food plants: sorrel, sheep's sorrel
Butterfly food plants: all nectar-rich flowers


Painted lady butterfly (Vanessa cardui)

Migrating in large numbers from North Africa in spring, this fast-flying butterfly has pale, buff-orange wings, the black tips marked with white spots. Look out for it from late March to October. It currently can't overwinter here, but that may alter with climate change.

Caterpillar food plants: thistles, nettles

Holly blue butterfly (Celastrina argiolus)

Holly blue numbers vary greatly due to a parasitic wasp. Until recently its range was confined to England and Wales, but now it's expanding and moving north.

Caterpillar food plants: holly, ivy
Butterfly food plants: sap, aphid honeydew


Comma butterfly (Polygonia c-album)

Named for the comma-shaped silver marks on the undersides of its wings, you can see commas in March and April. Offspring emerge as dazzlingly bright adults in July, or darker, more angular ones in August, before hibernating from around the end of September. The comma has made a spectacular comeback since the 1960s and is now found in England, Wales, the Isle of Man, the Channel Islands and the west coast of Ireland. It's moving north and west.

Caterpillar food plants: nettle, hops
Butterfly food plants: buddleja

This is a declining species. It's widespread across the UK, except northern Scotland, but it's in decline – numbers are down 37 per cent over the past 40 years, likely due to climate change.

Caterpillar food plants: grasses
Butterfly food plants: oregano


Red admiral (Vanessa atalanta)

Caterpillar food plants: clovers and bird's foot trefoil

Butterfly food plants: knapweed, ragwort, clover, oregano

Kate Bradbury says

All of these butterflies are on the wing from late July and through August. If you cut your buddleia down hard in May, then it will flower slightly later, to coincide with the key butterfly flight period.

Keeping plants well watered means more nectar – so be sure to keep the soil moist, especially in warm weather.
