Big Butterfly Count 2025 is underway - Butterfly Conservation
Calling all wildlife lovers – UK Butterflies need you!
This year, we’re not just launching a survey — we’re launching a nationwide rescue mission, and we need everyone to get involved.
Last summer, Britain’s butterflies sent an urgent SOS through Butterfly Conservation’s Big Butterfly Count.
The wildlife charity declared a Butterfly Emergency after results revealed a marked and deeply concerning decline in butterfly numbers, which were the lowest in the Count’s history.
The 2024 figures followed a pattern of long-term decline as butterflies struggle against a backdrop of habitat degradation, climate breakdown and pesticide use.
That’s why this year, we’re not just launching a survey — we’re launching a nationwide rescue mission, and we need everyone to get involved.
No lab coats. No science degrees. Just 15 minutes of your time
Butterfly Conservation’s Big Butterfly Count 2025 begins on Friday 18 July, and we’re calling on thousands of everyday heroes, from schoolkids to grandparents, dog walkers, hikers, even office workers on their lunch break, to take part.
Worryingly, 80% of butterflies have declined since the 1970s. These delicate icons of summer respond quickly to environmental change, making their decline a powerful warning sign of a planet in peril.
The good news? There is hope. With just 15 minutes of your time, you can help protect UK butterfly species for future generations.
The mission?
Spend 15 minutes in any outdoor space and count the butterflies and day-flying moths you see and submit your sightings to help build our interactive map.
That’s it. One small action that contributes to a much bigger effort to help save butterfly species and the ecosystems they support.
“This is a chance to turn curiosity into conservation and make a real contribution to protecting butterflies in the UK for generations to come,” said Dr Richard Fox, Head of Science at Butterfly Conservation. “Butterflies are beautiful, yes — but they’re also incredibly important bioindicators. This means that as they continue to disappear, as they have over recent decades, it indicates something is going seriously wrong in our natural world. We need to heed that warning and take action before it’s too late. If we lose butterflies, we lose more than beauty — we lose balance in our ecosystems and that will have serious repercussions for wildlife in the UK. Taking part in the Big Butterfly Count only takes 15 minutes and it’s something everybody can do. If you do one thing for nature this year, get out for the Count this summer! – Every count really does make a difference."
