28,043 butterflies spotted in Scotland last summer: can we beat that in 2024?

Butterfly Conservation issues rallying cry to people of Scotland

Last summer, citizen scientists in Scotland spotted 28,043 butterflies and day-flying moths during the Big Butterfly Count. Today, wildlife conservation charity, Butterfly Conservation, is issuing a rallying cry to people in the region to help beat that this year.

In 2023, people across Scotland did 5,087 Big Butterfly Counts, with Small White taking the top spot for species sightings. Scientists are hoping even more people will take part to help find out what’s happening with the region’s butterflies before the Count ends on Sunday 4 August.

It’s more important than ever that people take part this year. After analysing 50 years of data, researchers have discovered a clear northward spread for many species, including common garden favourites the Peacock, Comma and Holly Blue, the result of climate change creating warmer habitats for them to survive in.

Butterflies are indicators of the health of our natural environment – and with half of Britain’s butterfly species already threatened or near threatened with extinction, it’s never been more important to understand how these species are responding to the changing climate and to take action to protect them.


Dr Zoë Randle, Senior Surveys Officer at Butterfly Conservation explains: ‘We really need people across Scotland to get out for the Count to help us understand the impact of climate change on our most-loved butterflies.

“We’re relying on everyone, everywhere to spend just 15 minutes outdoors and let us know what they see. With species on the move, someone in Scotland might even be the first to spot a new species in their area!”

Whether done with friends and family, or in a moment of quiet calm and solitude, Butterfly Conservation’s Big Butterfly Count is free, fun and takes just 15 minutes in a sunny spot. It is open to anyone, of any age, in any part of the UK – towns, cities or the countryside. No green space is too small – a back garden, a small terrace or balcony with some pot plants, a public park, allotment or country lane are all important spaces to explore, track and report.

Last year more than 135,000 Counts took place up and down the country, with participants spending a combined four years counting butterflies in their gardens, local parks, urban community spaces, balconies, courtyards and in the countryside. The information gathered helps to inform conservation projects, government policies and supports other experts with their research and vital work to protect our planet.



This year’s Big Butterfly Count is already underway, running from Friday 12 July – Sunday 4 August.

On the Move: Scientists ask public to help track spread of butterfly species

  • Data shows butterflies are spreading northward due to climate change creating warmer habitats
  • Migratory Red Admiral now overwintering and classed as a UK resident with three fold increase in numbers 
  • New species spotted in new places, including the Holly Blue in Scotland and Jersey Tiger in central London
  • Citizen scientists are vital in discovering how garden favourite butterflies are on the move through the Big Butterfly Count


Leading wildlife charity Butterfly Conservation is today calling on people across the UK to take part in this year’s Big Butterfly Count (12 July – 4 August) and help scientists understand how climate change is moving butterflies.

After analysing 50 years of data, researchers have discovered a clear northward spread for many species, including common garden favourites the Peacock, Comma and Holly Blue, the result of climate change creating warmer habitats for them to survive in.

Another species on the move is the Jersey Tiger. Previously found only in south-west England, the striking day-flying moth has in recent years been spotted as far north as central London, gaining its spot in the Big Butterfly Count in 2021.

And at the other end of the scale, species such as the Scotch Argus in Scotland (above) are retreating northwards to stay in the cooler climes this butterfly prefers.

Butterflies are indicators of the health of our natural environment – and with half of Britain’s butterfly species already threatened or near threatened with extinction, it’s never been more important to understand how these species are responding to the changing climate and to take action to protect them.

To help scientists discover more about the movement and trends of where butterflies are living, the public are being asked to spend 15 minutes in any sunny spot and record the number and type of butterflies they see this summer.

Dr Zoë Randle, Senior Surveys Officer at Butterfly Conservation explains: “Thirty years ago you wouldn’t have seen a Holly Blue in Scotland, now it has expanded where it lives across the UK by 34%, increasingly spreading northward.

“And the Red Admiral, which was once a migratory species most commonly seen in southern England in the summer and then leaving for Europe in the winter, is now living in the UK all year round, resulting in a three-fold increase in their numbers. 

“We’re also seeing other species which have previously suffered severe declines, such as the Comma, recovering, with a huge increase of 94% in where it is found. These highly adaptable species are all able to move into new places as the climate warms, but for habitat specific species, these trends raise serious red flags. 

“Species that rely on particular habitats aren’t able to move as freely as our garden favourites. This means that if climate change continues, they could become trapped in isolated fragments of remaining habitat, unable to move and with their food plants at risk from adverse weather conditions, facing the very real threat of extinction.”

Butterfly Conservation Vice President, Chris Packham, who today launches this year’s Big Butterfly Count, explains: “Butterflies are on the move, and there’s no doubt that climate breakdown is behind these geographic shifts. 

“We know nature is running out of time, so we need to act now. We need you to get out for the Big Butterfly Count, let us know what you spot and where you spot it. You will be gathering the important data we need to see what the latest impacts are on our butterflies and moths, so that we can take the action needed to protect them.” 

Chris Packham is not alone in his support for the Big Butterfly Count, as President of Butterfly Conservation, Sir David Attenborough has shared poignant messages in his support of the Count over the years.

Sir David said: “The UK is a nation of amateur naturalists, and we have a proud tradition of celebrating and studying our wildlife.

“Every single person taking part in the Big Butterfly Count helps to build a picture of how butterflies are faring and how we can best conserve them. A few precious moments spent watching a stunning Red Admiral or Peacock butterfly feeding amongst the flowers in my garden never fails to bring me great pleasure.” 

Other famous faces to have taken part or supported the Big Butterfly Count over the last few years include His Majesty King Charles III, Her Royal Highness Princess Charlotte, Butterfly Conservation Vice President Dr Amir Khan, and even Winnie the Pooh!

Butterfly Conservation’s Big Butterfly Count is the largest citizen-science project of its kind and is a positive action everyone can do to help collect important scientific data, as well as enjoy time outdoors, connect with nature and have fun.

Whether done with friends and family, or in a moment of quiet calm and solitude, the Big Butterfly Count is free, fun and takes just 15 minutes. It is open to anyone, of any age, in any part of the UK – towns, cities or the countryside.

No green space is too small – a back garden, a small terrace or balcony with some pot plants, a public park, allotment, or country lane are all important spaces to explore, track and report.

Last year more than 135,000 Counts took place up and down the country, with participants spending a combined total of almost four years counting butterflies.

The information gathered helps scientists to understand how butterflies and moths are faring, informs conservation projects, government policies and supports other experts with their research and vital work to protect our planet.

Dr Zoë Randle said: “In total, over 1.5 million butterflies and day-flying moths were recorded in last year’s Count, where the Red Admiral reigned supreme with almost 250,000 sightings.

“We’re wondering whether someone this year will be the first to spot a new species in their area, and what the results will show for our butterflies and moths across the UK.”

This year’s Big Butterfly Count runs from Friday 12 July – Sunday 4 August.

One simple step can boost garden butterfly numbers by up to 93%, new study reveals

  • New six-year study proves that leaving areas of grass to grow long in gardens can increase butterfly numbers by up to 93%
  • This the first scientific evidence that wildlife-friendly gardening practices, such as having long grass and flowering ivy, boost the numbers and types of butterflies, particularly in urban areas and near farmland
  • The research is great news for gardeners and non-gardeners alike, proving the free and easy action of letting an area go wild can make a positive impact for butterflies

Letting parts of your garden grow wild with long grass can increase butterfly numbers by up to 93% and attract a wider range of species, according to new research from leading wildlife charity Butterfly Conservation.

The study, published in the journal Science of the Total Environment, provides the first scientific evidence that having long grass in your garden increases butterfly abundance and diversity. Creating such wild spaces may help to reverse the decline of these beautiful insects.

Undertaken by Butterfly Conservation scientists Dr Lisbeth Hordley and Dr Richard Fox, the research analysed butterfly sightings from more than 600 gardens across the UK, collected by members of the public over six years through the charity’s Garden Butterfly Survey.

The results show that gardens with long grass had a significantly higher number of butterflies recorded, with a greater variety of species, than those without.

Importantly, the biggest benefits of these wild spaces were found in urban areas and intensively farmed landscapes. In highly arable areas, gardens with long grass saw up to 93% more butterflies, and those in urban areas showed an increase of 18%.

The potential to provide wild spaces for butterflies and moths to thrive is huge. Gardens make up more than 728,000 hectares in Great Britain – the equivalent of over a million football pitches.

If each of these gardens had a space that was allowed to go a little wild, with grass growing long, it would make a huge difference for butterflies and moths, providing spaces for them to feed, breed and shelter.

While the research specifically studied gardens, the benefits to butterflies of long grass and wild spaces are likely to extend beyond the garden gate. Public green spaces such as parks, school grounds, allotments, and road verges, could also provide vital spaces for wildlife, and enable more people to see more butterflies if allowed to go a little wild.

Dr Richard Fox, Head of Science at Butterfly Conservation and co-author of the study, said: “Nature is in crisis; 80% of butterflies have declined since the 1970s, so we need to take action now to protect them.

“We wanted to be able to give tried and tested gardening advice that will benefit butterflies as we know lots of people want to help. This study proves, for the first time, that allowing a patch of grass to grow long will attract more butterflies into your garden.”

The study also found that the presence of flowering ivy in gardens increased the number of certain butterfly species, such as the Holly Blue, Red Admiral and Comma, which use ivy as a breeding habitat or nectar source.

Butterfly Conservation is calling for everyone to create their own Wild Space, no matter how big or small, to help butterflies survive and thrive. Through its Wild Spaces programme, the charity aims to transform 100,000 areas across the UK to help support butterfly populations.

Dr Fox added: “The simple act of creating wild spaces by allowing a patch of grass to grow long, or a border edge to go wild is free and easy to do, and can significantly boost butterfly numbers, especially in urban and agricultural settings where they are most under pressure. The benefits of each individual wild space are small, but if thousands of people get involved the boost to butterflies could be huge.

“Whether you have a large garden, a small patch of grass, a community or school space, or a balcony or window box, anyone, anywhere can help. We hope that our Wild Spaces programme will inspire people across the UK to take action and help to create a national network of butterfly-friendly habitats.”

Wild Spaces can be created by anyone, anywhere – from gardens to shared community spaces, balconies, terraces, or patios. No matter the size or location, every Wild Space can contribute to the recovery of butterfly populations and support biodiversity.

UK’s Butterfly Winners and Losers of 2023 Revealed

The latest results from the annual UK Butterfly Monitoring Scheme (UKBMS), led by wildlife charity Butterfly Conservation, the UK Centre for Ecology & Hydrology (UKCEH), British Trust for Ornithology (BTO) and the Joint Nature Conservation Committee (JNCC), show that 2023 was a mixed picture for butterflies, with some species soaring while others continued worrying declines.

Half the 58 species had a better than average year while the other half were below average at monitored sites. Species that flourished included Chequered Skipper, Brimstone, and Large Blue, which all recorded their best year since the UKBMS began in 1976. 

Another species recording its best-ever year was the Red Admiral, a migratory species that has begun to overwinter in the UK as the climate has warmed, making it a common visitor across all habitats, including gardens. Its numbers have increased by 318% at monitored sites since 1976.

At the other end of the scale were the Small Pearl-bordered Fritillary and garden favourite the Small Tortoiseshell, recording their lowest numbers in the 48 years of monitoring, declining by 71% and 82%, respectively since 1976.

Small Tortoiseshell had its worst year on record in England, second worst in Wales and joint fifth worst in Scotland in 2023, but did really well in Northern Ireland, logging its second best year.

The Large Blue, which was reintroduced to the UK after becoming extinct in the 1970s, recorded its best year yet, showing the conservation work with this species is really working. 

Other species that had a remarkable year include Brown Argus, Marbled White, Comma, Black Hairstreak, and Holly Blue, which all ranked in their top three best years since 1976. On the other hand, Cryptic Wood White, Grizzled Skipper, Pearl-bordered Fritillary, Grayling and Scotch Argus faced significant difficulties. 

The Green-veined White and Ringlet both had a poor year, perhaps suffering ongoing effects from the drought the previous summer. 

The UKBMS, which began in 1976, is one of the world’s longest-running insect monitoring schemes. 

Dr Richard Fox, Head of Science at Butterfly Conservation, said: “Butterfly numbers fluctuate naturally from year to year, largely due to the weather, but the long-term trends of UK butterflies are mainly driven by human activity, including habitat damage and destruction, pesticide use, pollution and climate change.

“By monitoring long-term butterfly trends we can learn about the impact of climate change and other factors on our native wildlife.” 

Dr Marc Botham, Butterfly Ecologist at the UK Centre for Ecology & Hydrology, added: “Butterflies are an indicator species, meaning they can tell us about the health of the wider environment, which makes the UKBMS data invaluable in assessing the health of our countryside and natural world in general.

” The mixed results this year emphasise the need for continued monitoring and conservation efforts to protect these important species and their habitats.”

Dr James Heywood, Breeding Bird Survey National Organiser at the British Trust for Ornithology, whose volunteers contribute to the UKBMS, commented: “In 2023, thousands of skilled volunteers monitored a record-breaking 3,316 sites across the UK, gathering valuable data that will help to inform conservation decisions for the future.

“We are incredibly grateful to each and every one of those people who carry out the monitoring and help us to maintain this highly valuable study.”

Chris Tuckett, Chief Officer for Strategy and Impact at JNCC, said: “The evidence produced through environmental monitoring, such as the UK Butterfly Monitoring Scheme demonstrates the vital role these schemes play in helping us understand the effects of pressures on the natural environment and, equally importantly, how efforts to address these pressures through nature conservation and recovery can be effective in reversing decline. 

“JNCC has supported these schemes, which involve thousands of dedicated volunteers, for over 30 years, and remains committed to continuing to support them in the future.”

The UKBMS now records data on over 3,000 sites per year and the resulting dataset is a crucial resource for understanding changes in insect populations and has provided significant insights into almost all aspects of butterfly ecology. 

As the UK faces the ongoing challenges posed by climate change and other environmental pressures, the work of the UKBMS and organisations like Butterfly Conservation, the UK Centre for Ecology & Hydrology, the British Trust for Ornithology and JNCC remains essential in monitoring and protecting precious butterfly populations and the habitats they depend on.

Counting butterflies reduces anxiety, new study proves

  • New scientific research reveals reduction in anxiety of almost 10% and improvements in mental wellbeing when taking part in the Big Butterfly Count
  • The first-of-its-kind study also shows citizen science activities can connect people with nature, a vital step towards conservation success and nature recovery

Leading wildlife charity, Butterfly Conservation, has today revealed that counting butterflies reduces anxiety by almost 10%, in new scientific research published in collaboration with the University of Derby. 

The pioneering study involved surveying people taking part in Butterfly Conservation’s Big Butterfly Count in 2022. The results demonstrate that briefly tuning into nature to count butterflies reduces anxiety by 9% on average, while also enhancing mental wellbeing. 

Researchers also found that spending just 15 minutes observing and counting butterflies boosted participants’ feeling of connectedness with nature. Noticing butterflies more often was sustained over 6-7 weeks after taking part.

How connected people feel to nature, known as nature connectedness, is directly correlated to how motivated they are to protect it. Therefore, the findings of this new study show that citizen science projects could play a vital role in nature’s recovery.

Dr Richard Fox, Head of Science at Butterfly Conservation, said: “While we have long known that there is a link between nature and human wellbeing, this study is the first to prove that the simple act of looking for and counting butterflies leads to a measurable decrease in anxiety. 

“The results suggest that citizen science projects such as the Big Butterfly Count can play a part in improving people’s mental health, as well as gathering important data on how butterflies are faring to inform our conservation work.”

Dr Carly Butler, a Researcher in Nature Connectedness at the University of Derby and lead researcher on the study, said: “Our study showed that even small periods of time spent watching and counting butterflies are beneficial, with the benefits of reduced anxiety and stronger nature connectedness being the same whether people carried out just one 15-minute count or took part multiple times.

“This is key in proving that simple, small pockets of time connecting with wildlife and nature have a profound and beneficial effect on how we feel.”

Participants reported a range of positive and negative emotions, including joy, fascination, sadness, and concern; the latter driven by not seeing as many butterflies as they expected and fear over what is happening to our planet.

Carly added: “Interestingly, the more intensely participants felt these emotions, the more their feeling of closeness to nature and noticing wildlife increased afterwards, with participants reporting they felt motivated to help butterflies and nature more, by doing things such as transforming their gardens into butterfly-friendly havens.”

In conclusion, Dr Richard Fox said: “In order to save wildlife and ensure nature’s recovery we need people to care, and we know that being connected to nature sparks these caring feelings and a desire to do something positive.

“This study indisputably shows that citizen science activities, such as spending just a few minutes counting butterflies, makes people feel more connected to nature – a vital step in the battle to save wildlife. 

“We’re at a tipping point, nature is in crisis, but we can all do something to help. Simple acts such as creating wild spaces to provide a haven for wildlife, or planting butterfly friendly plants in pots on a patio, terrace or balcony can have a positive impact.”

The Big Butterfly Count is Butterfly Conservation’s flagship citizen science activity, involving tens of thousands of participants across the UK spending 15 minutes in any sunny spot and recording the number and type of common butterflies and day-flying moths that they see.

This year’s Big Butterfly Count will take place from Friday 12 July – Sunday 4 August.

Butterfly numbers INCREASED this summer

Results of this year’s Big Butterfly Count revealed 

  • Wetter summer was good for butterflies, with average number of butterflies spotted highest for four years
  • However, new 13-year trend figures show a worrying long-term decline
  • Habitat loss biggest driver of decline; people urged to take action by creating a Wild Space

Results of Butterfly Conservation’s Big Butterfly Count 2023 have been released today, revealing a better picture for butterflies than had been feared. 

Overall, participants of the Big Butterfly Count enjoyed seeing more butterflies this year than in the previous four summers. In total, over 1.5 million butterflies and day-flying moths were recorded from 14 July – 6 August. After an all-time low in 2022 of just nine individual butterflies spotted per Count, this year saw an increase to 12 butterflies recorded on average per Count. 

However, this good news is in contrast with what the long-term trends are revealing. Released for the first time this year, these show that since the Big Butterfly Count started 13 years ago, many species have significantly decreased.

It is a further warning sign that nature everywhere is in crisis – butterflies, as well as forming a vital part of the food chain, are considered significant indicators of the health of the environment.

Following last summer’s heatwave and drought, scientists at Butterfly Conservation called on the public to help them understand the effect the extreme weather had on the UK’s butterflies. People responded in their thousands, with almost 95,000 citizen scientists taking part in this year’s Big Butterfly Count, conducting 136,719 15-minute Counts in gardens, parks, school grounds and the countryside. 

Dr Zoe Randle, Senior Surveys Officer at Butterfly Conservation, said: “It’s wonderful that so many people have been out enjoying spotting butterflies. We had huge support for the Big Butterfly Count this year, and thanks to the many people who went out during those sunny intervals, we now know that the effects of last year’s drought were not as bad for butterflies as we had feared.

“The mixed weather this year has helped as there has been an abundance of green food plants available for caterpillars, and plenty of nectar-rich flowers for adult butterflies. However, while the number of butterflies recorded this summer has been the highest since 2019, the longer-term trends show worrying declines for some of the UK’s most common butterfly species.”

The most-seen species this year was the Red Admiral, with 248,077 recorded – an increase of 338% on last year’s Count and the first time the species, which is increasing in the UK as a result of climate change, has taken the top-spot.

Gatekeeper was next, with 222,896 sightings. This represents a 12% increase on last year and is a small, but welcome, boost for a species that has decreased by 28% since the Count began. 

The Whites took the third and fourth spot, with 216,666 sightings of Large Whites and 190,506 of Small Whites, an 11% and 15% increase on 2022 respectively. Holly Blue had another good summer, with numbers up 66% on 2022, in keeping with its longer-term Big Butterfly Count trend of a 41% increase.

Species that saw a decline from last year include Ringlet, Common Blue and Speckled Wood, all of which also show long-term declines.

Although its numbers hardly changed compared to summer 2022, Green-veined White has the most severe Big Butterfly Count trend in the longer term, a decrease of 61%. 

Dr Richard Fox, Head of Science at Butterfly Conservation, explained: “One of the biggest threats butterflies in the UK face is habitat loss. While the weather certainly has an impact on numbers from year to year, butterflies, moths and many other species can generally cope with variable weather. What they can’t cope with is habitat destruction.

“Butterflies need a place to live. If they can feed, breed and shelter, they can thrive. By creating a Wild Space in your outdoor area you can help to reverse the massive losses of wildlife-friendly habitat and start to turn around the fortunes of our declining butterflies.”

Anyone, anywhere, can create a Wild Space. Whether it’s leaving a patch of long grass in your garden or planting a small selection of nectar rich plants on a balcony, the opportunities are vast and everyone can make a difference. 

Dr Richard Fox concluded: “Nearly 137,000 Big Butterfly Counts were recorded this summer and if every single person who helped with the Count creates a Wild Space, we can build a UK-wide network of spaces for butterflies to feed, breed and shelter. By creating a Wild Space everyone can make a difference and help butterflies and moths thrive.”

Butterfly Conservation has free resources and guidance on creating a Wild Space available, including accessible, tailored, simple advice for anyone to have a go.

Small White most spotted Butterfly in Scotland

Results of Butterfly Conservation’s Big Butterfly Count 2023 have revealed that Small White takes the top spot in Scotland this year, and a better picture for butterflies than had been feared has emerged. 

Following last summer’s drought, scientists at Butterfly Conservation called on the public to help them understand the effect the extreme weather had on the UK’s butterflies. People responded in their thousands, with 3,295 citizen scientists in Scotland taking part in this year’s Big Butterfly Count, conducting 5,087 15-minute Counts in gardens, parks, school grounds and the countryside. 

This year, those participants recorded more than 28,000 butterflies and day-flying moths between 14 July – 6 August. On average, people in Scotland spotted six individual butterflies per Count, very similar to the 2022 event.

However, UK wide long-term trends, revealed for the first time this year, show that since the Big Butterfly Count started 13 years ago, many species have significantly decreased.

It is a further warning sign that nature everywhere is in crisis – butterflies, as well as forming a vital part of the food chain, are considered significant indicators of the health of the environment.

Dr Zoe Randle, Senior Surveys Officer at Butterfly Conservation, said: “It’s wonderful that so many people have been out enjoying spotting butterflies.

“The mixed weather this year has helped as there has been an abundance of green food plants available for caterpillars, and plenty of nectar-rich flowers for adult butterflies. However, while the number of butterflies recorded across the UK this summer has been the highest since 2019, the longer-term trends show worrying declines for some of the most common butterfly species.”

The top five butterfly species spotted in Scotland were Small White, Large White, Peacock, Small Tortoiseshell and Meadow Brown. 

Comma also did well, showing an increase of 41% and experiencing its best summer in Scotland since the Big Butterfly Count began. This species suffered a severe decline in the twentieth century and has subsequently made a comeback, and has expanded its range rapidly northwards. 

Holly Blue also had its best ever Big Butterfly Count results in Scotland this summer and increased by 118% on 2022 levels. This species is a relatively recent arrival, becoming established in Edinburgh in 2006 and in Ayr in 2008. 

However, Scottish sightings of Common Blue, Ringlet and Six-spot Burnet were down compared to 2022. Speckled Wood recorded its lowest numbers in Scotland since the Big Butterfly Count began, and dropped 49% on 2022 levels. 

Dr Richard Fox, Head of Science at Butterfly Conservation, explained: “One of the biggest threats butterflies in the UK face is habitat loss. While the weather certainly has an impact on numbers from year to year, butterflies, moths and many other species can generally cope with variable weather.

Extinct Butterfly Makes Remarkable Return

Northern Brown Argus butterfly discovered after 100 year absence

A once locally-extinct butterfly has made a remarkable return to Stirlingshire after a 100 year absence, Butterfly Conservation and The Future Forest Company has revealed. 

The Northern Brown Argus was once found in abundance throughout the Ochil Hills, but due to habitat loss including overgrazing, was believed extinct in Stirlingshire and across much of its former range.

Very few colonies remain in the Ochils, with small numbers clinging on above the village of Alva in Clackmannanshire, living on steep crags where sheep cannot graze the food plants required by their caterpillars too heavily. 

However, in a remarkable discovery, a volunteer from Butterfly Conservation found Northern Brown Argus in her garden in Blairlogie, just inside the Stirlingshire border, after planting Common rock-rose, the only plant eaten by Northern Brown Argus caterpillars. 

This sparked hope for the once locally-extinct species. Staff and volunteers from Butterfly Conservation and The Future Forest Company conducted a series of searches on the hillside at the award-winning Dumyat Estate in Blairlogie, discovering a few small colonies of the butterfly on the steep hills. 

In another exciting turn of events, the Northern Brown Argus is now confirmed to be breeding at the site, which is owned by The Future Forest Company, giving hope for the return of this species across its former habitat. 

David Hill, Conservation Manager at Butterfly Conservation, said: “This is a once-in-a-lifetime event, the reemergence of a previously locally-extinct species in its former habitat is incredibly special and rare.

“We’re committed to protecting the Northern Brown Argus and helping it to thrive, with hopes that it will spread across its former home and stretch right across the Ochil Hills once again.”

Lindsay Mackinlay, The Future Forest Company’s Head of Biodiversity, explained: “We are delighted that this rare butterfly can once again be spotted on the hills below Dumyat. We hope to work in partnership with Butterfly Conservation to monitor its numbers in the coming years. 

“With the help of volunteers, The Future Forest Company is starting to clear the invasive scrub that is threatening the Common rock-rose plants which this beautiful butterfly depends on, however, more conservation work is required to ensure the long-term survival of this species at Dumyat.

“We have a biodiversity crisis on our hands and everyone can play a part in reversing this, including the private sector. That’s why we are inviting any company that wants to help ensure a future for wildlife at Dumyat, or through our other exciting projects, to get in touch and help transform our landscapes into wildlife havens for local people.”

The State of UK Butterflies Report in 2022, published by Butterfly Conservation, revealed that Northern Brown Argus suffered a 58% decline in abundance between 1979 and 2019, and a 43% decline in distribution during the same time period.

The species is mostly found across Scotland and requires short grassland managed by light-grazing to thrive, however, much of its former habitat has been lost to overgrazing, lack of grazing or encroachment of scrub and woodland. 

Butterfly Conservation and The Future Forest Company are working together to protect the fragile colonies and extend the range of this enduring butterfly by planting more Common rock-rose for its caterpillars to feed on and creating more habitats for it to thrive.

UK Sees Red!

Red Admirals take surprising early lead in 2023 Big Butterfly Count 

Wildlife charity, Butterfly Conservation, has today revealed a huge surge in sightings of the Red Admiral, a migrant species of butterfly, as the Big Butterfly Count enters its final week. 

The Red Admiral is currently flying high with 170,000 sightings reported so far*, an impressive increase of 400% on the same period last year. 

It is definitely a ‘Red Admiral year’, with people throughout the country reporting seeing the butterfly while taking part in Butterfly Conservation’s Big Butterfly Count.

The Red Admiral is a familiar and popular butterfly across the UK. It is a garden favourite and found in all types of habitat. However, what may come as a surprise to many is that this small but mighty butterfly is a migrant species, travelling to the UK from North Africa and continental Europe! 

There can be no doubt that climate change is the driver behind a long-term increase in Red Admiral numbers. 

Each spring, and continuing through the summer, Red Admirals migrate north where the females lay eggs. Consequently, there is an emergence of fresh butterflies from July onwards. 

However, in recent years, scientists are seeing an indication that numbers have increased, and that the species is now overwintering in the UK, particularly in the South of England. 

With temperatures increasing, the Red Admiral’s need to return to its southerly winter habitat is reducing, which means it is possible we will see a greater number of the species spending the winter in the UK. 

This year’s early results show why the Big Butterfly Count is so important in helping scientists to understand how the weather and changing climate are affecting butterflies. 

Dr Zoë Randle, Senior Surveys Officer at Butterfly Conservation explains: “We’ve been surprised to see the Red Admiral taking the lead, however with the increased frequency of warm weather, the UK may well become a permanent home for this species. 

“The results so far show just how vital the Big Butterfly Count is. We couldn’t get the depth and breadth of data we’re collecting without the help of the general public. We’re calling on people across the UK to please get out for the Count and record your butterfly sightings over the next few days.

“With climate change here to stay, we need people to take part more than ever before and help us understand how extreme weather is affecting our butterflies.” 

Butterfly Conservation’s Big Butterfly Count isn’t over yet!

So far, citizen scientists across the UK have completed more than 85,000 Counts and recorded over 1 million butterflies and day-flying moths. 

The Big Butterfly Count runs until Sunday 6 August and scientists at Butterfly Conservation are keen to see whether the influx of Red Admirals continues, and how they are dispersed around the UK. 

Whether done with friends and family, or in a moment of quiet calm and solitude, the Big Butterfly Count is free, fun and takes just 15 minutes. It is open to anyone, of any age, in any part of the UK – towns, cities or the countryside.

No green space is too small – a back garden, a small terrace or balcony with some pot plants, a public park, allotment or country lane are all important spaces to explore, track and report.

Scientists ask public to help discover effect of extreme weather on butterflies in Scotland

Wildlife charity, Butterfly Conservation, is today calling on people across Scotland to take part in this year’s Big Butterfly Count (14 July – 6 August) to help scientists understand the impact of climate change on the country’s most-loved butterflies. 

Last year’s record temperatures, heatwave and drought caused some of the plants that caterpillars feed on to wither and die. To help scientists discover what the ongoing impact of this extreme weather has been, the Scottish public are being asked to spend 15 minutes in any sunny spot and record the number and type of butterflies they see.

Last year, people across Scotland carried out 3,633 counts as part of the Big Butterfly Count, spotting 24,111 butterflies and day-flying moths. The most commonly spotted species across the country included Meadow Brown, Small White and Ringlet. Scientists need to know how these and other species are faring, and are relying on the Scottish public to help.

Butterflies are indicators of a healthy natural environment – with half of the UK’s butterfly species already threatened or near threatened with extinction, it’s never been more important to understand how our insects are responding to the changing climate and to take action to protect them.

Dr Zoë Randle, Senior Surveys Officer at Butterfly Conservation explains: “This is a vital year for the Big Butterfly Count. We know that the previous extreme summer droughts in 1976 and 1995 took a heavy toll on butterflies and numbers crashed the following year, taking almost a decade to recover.

“The data collected in Scotland during this year’s Big Butterfly Count will give us a valuable insight into what the effect of the most recent extreme weather has been, and how we might be able to better protect our beautiful butterflies. With climate change here to stay, we need people in Scotland to take part more than ever before.”

Butterfly Conservation’s Big Butterfly Count is the largest citizen-science project of its kind and is a positive way that everyone can help. As well as contributing to important scientific data collection, taking part in the Count is a great way to enjoy time outdoors, connect with nature and have fun.

Butterfly Conservation Ambassador, Dr Amir Khan is one of many famous faces supporting the Big Butterfly Count. He explains: “Getting outside in nature and watching butterflies is a wonderful experience, not only does it spark joy and lower anxiety, you also know that you’re having a big impact on informing important conservation decisions.

“Spending time in nature is proven to be beneficial to our mental health, it can alleviate stress, boost mood and energy, and enhance feelings of happiness.”

Dr Khan is not alone in his advocacy of nature’s medicine, as President of Butterfly Conservation, Sir David Attenborough, has shared poignant messages in his support of the Big Butterfly Count over the years.

Sir David said: “A few precious moments spent watching a stunning Red Admiral or Peacock butterfly feeding amongst the flowers in my garden never fails to bring me great pleasure.” 

Other famous faces to have taken part or supported the Big Butterfly Count over the last few years include His Majesty King Charles III, Her Royal Highness Princess Charlotte, Butterfly Conservation Vice President Chris Packham (who today launches this year’s Big Butterfly Count), and even Winnie the Pooh!

Whether done with friends and family, or in a moment of quiet calm and solitude, the Big Butterfly Count is free, fun and takes just 15 minutes. It is open to anyone, of any age, in any part of the UK – towns, cities or the countryside.

No green space is too small – a back garden, a small terrace or balcony with some pot plants, a public park, allotment or country lane are all important spaces to explore, track and report.

Last year almost 100,000 Counts took place across the UK, with participants spending a combined 2.5 years counting butterflies in their gardens, local parks and in the countryside. The information gathered helps to inform conservation projects, government policies and supports other experts with their research and vital work to protect our planet.

Dr Zoe concludes: “We know 80% of butterflies in the UK have declined since the 1970s. Which means there are fewer butterflies to be seen than in years gone by.

“However, even if you don’t see any butterflies during your Count, we still want you to tell us! We need to know where there AREN’T any butterflies just as much as where there are, so please still log your result and then pick another day or location and try again. There are no limits on how many times you can take part.”

David Forbes Nixon OBE, Chairman of the DFN Foundation which sponsors the Big Butterfly Count, said: “The DFN Foundation is thrilled to once again sponsor the much-anticipated Big Butterfly Count this year, supporting Butterfly Conservation in their crucial work protecting butterflies from extinction.

“I am delighted that Undershaw School, an initiative of the DFN Foundation, will be taking a leading role in launching this year’s Big Butterfly Count. The school will host an action-packed event, educating pupils and the local community on the importance of biodiversity and conservation through the enchanting world of butterflies. 

“Summer is a glorious time to enjoy the great outdoors in the UK, and so I encourage everyone to get involved with this year’s Big Butterfly Count, either with friends and family or setting off on a solo adventure to enjoy a moment of calm and reconnect with nature.

“Not only will it make you feel good, but it will also be invaluable in helping to save species of butterflies and protect our environment for future generations to enjoy.”

This year’s Big Butterfly Count runs from Friday 14 July – Sunday 6 August. For more information and to take part simply visit www.bigbutterflycount.org or download the free Big Butterfly Count app.

Hot, dry summer impacts UK butterfly populations

The heatwave and drought of summer 2022 has had a major negative impact on some UK butterfly species, a study has confirmed.

The latest results from the annual UK Butterfly Monitoring Scheme (UKBMS) led by Butterfly Conservation, the UK Centre for Ecology & Hydrology (UKCEH), British Trust for Ornithology (BTO) and Joint Nature Conservation Committee (JNCC), show that the extreme weather experienced across much of the UK in the summer of 2022 has had a significant impact on some butterfly species.

The Green-veined White, Small White, Small Tortoiseshell, Peacock and Brimstone, all familiar garden and countryside butterflies, appeared in good or average numbers during the spring and early summer, but numbers in the subsequent generations were greatly reduced following the widespread drought conditions, and scientists fear that there will be similar negative impacts on other butterfly species when they start to emerge in 2023.

Drought impacts the offspring of the butterflies that are flying during the hot dry weather by causing the plants that caterpillars rely on for food to wither and die. Without sufficient food, many caterpillars will fail to survive, leading to lower numbers of butterflies in the next generation.

For some of the UK species that have more than one generation in a year, the resulting major decline in numbers has already been seen. However, for others, the next generation isn’t on the wing until this summer, meaning there could be noticeably fewer butterflies around in 2023.

It’s not the first time butterflies have been affected by drought in the UK. Data gathered by the UKBMS has shown serious negative impacts of droughts on butterflies in 1976 and 1995. Some species have never recovered their former abundance levels after the 1976 drought, although habitat destruction is likely to be a major factor in their failure to bounce back.

The difference in 2022’s drought compared to 1976 is that nowadays most UK butterfly species are already in decline. Butterfly Conservation’s recently published State of the UK’s Butterflies 2022 report revealed that 80% of butterflies have declined in abundance, distribution or both since the 1970s.

With droughts predicted to become more frequent and severe in the UK as climate change continues, some butterfly species may be pushed towards extinction.

Butterfly Conservation’s Head of Science, Dr Richard Fox, said: “Overall, the data for 2022 tells us that it was an average year for butterflies. However, it was a year of two halves with butterflies seen early and in about average total numbers (compared to the last 10 years) from April – July but then in greatly reduced abundance after the summer heatwave and drought.

“In general, warm, sunny weather is good for butterflies as they can be active, finding food, mating and laying eggs. But drought is a major problem as plants wither and die, meaning female butterflies may struggle to find anywhere to lay their eggs, or there is not enough food for the caterpillars when they hatch.

“The knock-on effect is fewer butterflies in the following generation. We have already seen an indication of this in the 2022 data for some of those species with a generation that flies in late summer and autumn, and sadly we can expect to see a decline in numbers of other species in 2023 too.”

The meticulously gathered UKBMS data show that, despite these concerns, 2022 was a good year for some species, including Purple Emperor, Large Blue, Chequered Skipper and Dark Green Fritillary, all of which have been the focus of targeted conservation work over the last few years. However, scientists issued a word of caution, as we have yet to see the result of the drought on these species because the next generation will not emerge until this summer.

There is much work to be done to conserve threatened species of butterfly in the UK, and the UKBMS data helps target those species most in need of conservation work.

Butterfly populations fluctuate naturally from year to year, largely due to the weather, but the long-term trends of UK butterflies are mainly driven by human activity, particularly the deterioration of habitats due to inappropriate management and pollution, and climate change.

Conservation efforts can make a real difference to local populations and working on threatened species in key landscapes to deliver nature recovery is a priority.

Dr Marc Botham, Butterfly Ecologist at the UK Centre for Ecology & Hydrology, said: “In 2022 we collected data from over 3,000 sites and we are incredibly grateful to the thousands of volunteers who carry out monitoring and maintain this invaluable long-term dataset.

“This enables scientists to measure how butterflies are faring as well as assessing the health of our countryside generally. The UKBMS data are vital in assessing the effectiveness of government policies and progress towards the UK’s biodiversity targets.”

Nature Minister Trudy Harrison said: “Our beautiful butterflies are at risk from a changing climate and human activity. We have set out clear steps to enable nature’s recovery through our Environmental Improvement Plan and Pollinator Action Plan, which will help us meet our legal target to halt the decline in nature by 2030.

“The impacts of warm and dry weather last year are cause for concern, but it is encouraging that the last decade has seen most species stabilise. In particular, I welcome the findings that the Large Blue and the Purple Emperor, two wonderful and unique species people may recognise from Wild Isles, both experienced their second best year on record in 2022.”

Dr James Heywood, Breeding Bird Survey National Organiser at the British Trust for Ornithology, whose volunteers collect butterfly data through the Wider Countryside Butterfly Survey, said: “These data are incredibly valuable as butterflies are indicators of the health of our natural environment and therefore the information gleaned from the UKBMS data is not just used to help understand and conserve butterflies, but also to help understand and protect the wider ecosystem on which so many birds, mammals and other species rely.”
