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.

Public asked to become citizen scientists in annual Star Count to map light pollution in our skies 

  • CPRE, the countryside charity, is calling on people to take part in Star Count, the country’s biggest annual citizen science project of its kind, which takes place from 26 February to 6 March 
  • A clear view of the night sky helps balance our mental health and boost emotional wellbeing – but light pollution is blotting out the stars and obstructing our ability to connect with nature 
  • Lockdown produced clearer, darker skies but experts fear it was a temporary reprieve 

People are being asked to take part in an annual Star Count to record how clear our view is of the night sky. CPRE, the countryside charity, is working with the British Astronomical Association’s Commission for Dark Skies to map light pollution levels across the country. 

In the biggest citizen science project of its kind, people are being asked to count the number of stars they see in the Orion constellation to help map the best and worst places in the UK to enjoy a star-filled night sky.

The results will be compared with 2021’s findings, gathered during lockdown, which revealed a notable drop in the number of people experiencing severe light pollution given urban areas were much quieter and fewer large buildings were in use. 

A clear view of a star-filled night sky has a hugely beneficial effect on our mental health and, like access to other forms of nature, helps reduce stress and increase a sense of peace and wellbeing. Research has even shown that regularly spending time looking at the stars can lower blood pressure and reduce depression. Yet, the night sky, which is a hugely significant part of our natural environment, has no legal protection.  

Tom Fyans, deputy chief executive of CPRE, the countryside charity, said: ‘The night sky is one half of our experience of nature; but we don’t often think of it like that. In and of itself, it helps balance our mental health and boost our emotional wellbeing. Recollect that experience of a starry sky and you instinctively know it soothed you. 

‘But our view of the night sky – and all the benefits it undoubtedly brings – is being blotted out by light pollution. Like all forms of pollution, it is damaging our mental and physical health, and also having a severe impact on wildlife. Yet, it is a form of pollution that is allowed to increase year on year without any effort being made to control the damage it is causing.’ 

In 2021, over 7,000 people took part in CPRE’s Star Count. The proportion of people reporting ‘severe light pollution’, defined as ten stars or fewer being visible to the naked eye in the Orion constellation, had declined from 61% to 51%.

The proportion of ‘truly dark skies’, defined as over 30 stars being visible within the Orion constellation, had increased from 3% to 5%. This was likely due to the count taking place during lockdown, with reduced levels of artificial light leading to a clearer view of the night sky. 

Now people are being urged to once again come together for one of the nation’s biggest citizen science projects to help discover if light pollution has increased since the end of lockdown – and where the best views of the stars can be found.

Emma Marrington, CPRE dark skies campaigner, said: ‘We need your help to find out if light pollution has increased over the past year and if more people are experiencing darker night skies.

“The results from Star Count will help us create a map of where star-spotters are enjoying deep, dark star-filled skies. By showing on a map where light pollution is most serious, we can work with local councils and others to decide what to do about it. 

‘Star Count is a great way to switch off from the distractions of daily life and reconnect with nature – and by taking part as a citizen scientist, you can help us protect and improve everyone’s view of a clear, sparkling night sky.’ 

Light pollution means many people only experience a limited view of the night sky, and it also disrupts wildlife’s natural patterns. By showing where views are most affected by light pollution, the evidence can be used to help protect and enhance the nation’s dark skies, improving our health, wellbeing, wildlife and the environment. 

Bob Mizon, of the British Astronomical Association’s Commission for Dark Skies, said: ‘The night sky is a great antidote to the stresses of modern life; you go out, look up and suddenly everything is calm. The stars made every atom in our bodies; they are our chemical parents. They’re intimately connected to us and even in these light polluted days people have a real desire to see the stars. 

‘Just as we have an affinity with trees and the rest of nature, we have a connection to the night sky. It is literally 50 per cent of our environment – from east to west – and it is the only part of our environment that has no protection in law.

People are very rapidly coming to the conclusion that what we do to the environment has a direct impact on our wellbeing. The same as coral reefs dying off and rivers clogged with plastic bags – one more aspect of our impact on the environment is our pollution of the night sky and yet it is completely unprotected.’
