10 ways to save butterflies as numbers plummet due to pollution and climate change

Some are flamboyant exhibitionists, others are furtive lurkers who blend in with their surroundings. Coloured vibrant orange or just plain beige, butterflies fluttering around a lush garden or wild meadow are always an idyllic summer sight.

But experts say numbers are plummeting and time is running out to save the beautiful insects from extinction.

Pollution and climate change are blamed for the decline of 76 per cent of Britain’s butterflies since 1978. Now two-fifths of British butterflies are at risk of dying out.

The latest Red List for British butterflies shows many beautiful native species are under threat from a myriad of problems including climate change, nitrogen pollution and landscape change.

“The news hurts,” says naturalist and nature writer Matthew Oates, who became hooked on butterflies from the age of nine. “Butterflies are absolutely fascinating and captivating. Nothing they do is random. They are really complex, strong creatures.

“We must never give up trying to save them. It’s not a lost cause. Small actions, such as growing a buddleja in a pot in a garden or balcony, really helps. Imagine a summer garden with no butterflies?”

Dr Richard Fox, head of science at Butterfly Conservation, echoes Matthew’s call. “The message is clear: sustained, targeted conservation efforts can reduce the extinction risk of threatened butterfly species.

“With the extinction risk increasing for more species, much more must be done to protect our butterflies from the effects of changing land management and climate change. Without action it is likely that species will continue to be lost.”

The decline of butterflies is an ominous sign for many more of Britain’s animals and plants, as Dr Fox explains that because butterflies are an important indicator species, seeing less of them is a sign other wildlife is in crisis too.

They also play crucial roles in the food chain and pollinate plants. So what can we do to save British butterflies?

Dr Fox shares his expert tips to help Britain’s 59 resident butterfly species.

1 Create a butterfly base in your garden

Butterflies will visit any garden, however small, if they can feed from nectar plants. And a well-planned garden can attract more than 20 species of butterfly. To attract butterflies, plant nectar plants in sunny, sheltered spots (as they like warmth) choose a variety of plants to attract different species, put the same types of plant together in blocks, and create a safe space for butterflies, moths and caterpillars to shelter by leaving a pile of logs in a quiet corner of the garden.

2 Plant for the seasons

Butterflies need flowers throughout the seasons; spring flowers are vital for butterflies coming out of hibernation, while autumn flowers help them build reserves for winter. Good plants for summer nectar for butterflies include buddleja shrubs (otherwise known as the butterfly bush), lavender, verbena bonariensis - which stands up to a metre tall - perennial wallflower, and marjoram herbs.

3 Plant carefully

Plant roses, shrubs or mid-sized perennials like buddleja in the centre of borders, and put taller plants like verbena bonariensis around the outside.

4. Look after your garden well

Gardeners can help butterflies by prolonging plants’ flowering by deadheading their flowers, mulching with organic compost and regularly watering plants.

5. Don’t use insecticides and pesticides

Insecticides and pesticides kill butterflies, as well as other pollinating insects and ladybirds, ground beetles and spiders, so try to avoid using them.

6. Don’t buy peat compost

Peat bogs are home to many important animals and plants, including the endangered Large Heath butterfly, which is declining across Europe. Instead of using peat compost, there are good alternatives available at garden centres.

7. Let a patch of grass grow long

You don’t have to let your whole garden grow wild, but if you let at least a patch of grass grow long, it can help attract insects including butterflies - nettles are good!

8. Don’t forget caterpillars

Remember to add a variety of caterpillar foodplants to your garden, like native shrubs. Caterpillars need foodplants to survive, and butterflies will be attracted to your garden to lay their eggs. Another benefit is that the more caterpillars you have, the more birds you’re likely to attract to feed on them. Plant trees like holly, alder, buckthorn, and herbaceous plants like broom, ivy, nasturtium, and hop, and remember butterflies and caterpillars also like plants we don’t like, such as nettles and thistles.

9. Even a small pot will help

If you haven’t got a garden, you can still help save butterflies - even a small plant pot on a doorstep or balcony could help butterflies get from one area of habitat to the next.

10. Take part in the Big Butterfly Count

You can also help conservationists learn more about what’s happening to our butterflies by taking part in the Big Butterfly Count (bigbutterflycount.butterfly-conservation.org), the world’s largest butterfly survey, which runs from 15 July to 7 August. All you have to do is spend 15 minutes in a sunny spot and record the amount and type of butterflies you see.
