BUTTERFLY EMERGENCY!

Big Butterfly Count results reveal lowest numbers on record

  • Butterfly Conservation calls on Government to declare a ‘Nature Emergency’ and act now by banning toxic neonicotinoid pesticides, before it’s too late
  • Butterfly Conservation’s Big Butterfly Count 2024 saw the lowest number of butterflies spotted per Count in its 14-year history
  • A third of species had their worst year on record ever
  • More than 9,000 Big Butterfly Counts reported not seeing a single butterfly

Wildlife charity Butterfly Conservation has today declared a national ‘Butterfly Emergency’, with results of this summer’s Big Butterfly Count showing a marked and hugely concerning decline in numbers.

Overall, participants spotted just seven butterflies on average per 15-minute Count, a reduction of almost 50% on last year’s average of 12, and the lowest in the 14-year history of the Big Butterfly Count.

It was the worst summer in the Count’s history for Common Blue, Holly Blue, Green-veined White, Small White, Small Tortoiseshell, Painted Lady and Scotch Argus. And the majority of species (81%) showed declines in the number seen this year compared with 2023.

In total, just over 935,000 butterflies and day-flying moths were recorded across the UK from 12 July – 4 August, down almost 600,000, equivalent to more than a third of 2023’s total, and 9,000 Counts were logged as seeing zero butterflies, the highest in the citizen science programme’s history.

These figures have alarmed scientists and resulted in the charity declaring a nationwide ‘Butterfly Emergency’.

Dr Richard Fox, Head of Science at Butterfly Conservation, said: “The previous lowest average number of butterflies per Count was nine in 2022, this latest figure is 22% lower than that, which is very disturbing.

“Not just that, but a third of the species recorded in the Big Butterfly Count have had their worst year on record, and no species had their best. The results are in line with wider evidence that the summer of 2024 has been very poor for butterflies.

“Butterflies are a key indicator species; when they are in trouble we know that the wider environment is in trouble too. Nature is sounding the alarm call. We must act now if we are to turn the tide on these rapid declines and protect species for future generations.”

Butterfly Conservation is writing an open letter to Steve Reed, Secretary of State for Environment, Food and Rural Affairs, calling for the Government to act now for nature by declaring a ‘Nature Emergency’ and banning butterfly-killing neonicotinoid pesticides once and for all, with no exceptions, before it’s too late.

Dr Fox explains: “When used on farmland, these chemicals make their way into the wild plants growing at field edges, resulting in adult butterflies and moths drinking contaminated nectar and caterpillars feeding on contaminated plants.

Many European countries have already banned these chemicals, it’s time for the UK to follow suit and put the natural world first. If we don’t act now to address the long-term drivers of butterfly decline, we will face extinction events never before seen in our lifetime.”

More than 85,000 citizen scientists took part in Butterfly Conservation’s Big Butterfly Count this year, submitting 143,241 Counts. This is equivalent to 35,810 hours, or four years worth of time spent counting, in gardens, parks, school grounds and the countryside.

Dr Richard Fox concluded: “If every single person who helped with the Count this summer signs our letter to the Government, we could prevent the very real and pressing threat of species becoming extinct in our lifetime.”

Note:

Ringlet, Marbled White and Six-spot Burnet appeared to have fared well in the Big Butterfly Count this year compared to 2023, however, this was due to their peak flight periods coinciding with the count. Over the course of the whole summer, these species also seem to have fared worse than usual.

To account for annual variation in flight periods, which are heavily influenced by the weather, Butterfly Conservation has produced a fourteen-year trend (2011–2024) for Big Butterfly Count species which can be seen in the results table. 

This shows that although these species fared well this year, the long-term picture for the two butterfly species is very different. Over the last 14 years Ringlet has declined by 47% and Marbled White by 18%.

Overall, the 14-year trends show that 11 species (65%) are declining, and three species (18%) are increasing, these are Red Admiral, Holly Blue and Small Copper.

Scottish Government announces support for plan to stage the Commonwealth Games in Glasgow

The Scottish Government has written to Commonwealth Games Scotland (CGS) to announce its support for their proposal to host the event in 2026.

Health Secretary Neil Gray outlined the decision in a letter to CGS chairperson Ian Reid following detailed consideration of the concept for a scaled-down version of the Games.

Commonwealth Games Scotland will now decide if they wish to proceed with their proposal before it is considered by the Commonwealth Games Federation.

Mr Gray said: “The fact that Glasgow was asked to step in and host the 2026 Games is testament to Glasgow and Scotland’s fantastic reputation for hosting international events.

“That said, we have been clear that our financial resources are limited. The Scottish Government has conducted a thorough assessment of Commonwealth Games Scotland’s proposal for Glasgow to host the 2026 Commonwealth Games.

“That assessment has been conducted alongside Commonwealth Games Scotland, the Commonwealth Games Federation, Glasgow City Council, the UK Government and, most recently, Commonwealth Games Australia.

“The collaboration has been extremely positive and productive and has resulted in the finalisation of a strong event proposal that will help to support a new future for the Commonwealth Games and deliver economic and sporting opportunity for Scotland.  

“On that basis, I was pleased to write to Commonwealth Games Scotland today to inform them that the Scottish Government will give its support for the proposal.

“In 2026 all eyes will once again be on Glasgow, and I have every confidence that Scotland’s largest city will provide a fitting platform for some of the world’s top athletes.”l

The Secretary of State for Scotland @ianmurraymp has welcomed the news the Commonwealth Games will come to Glasgow in 2026, with the UK Government supporting the security costs of the event:
