Can you take part in a butterfly count? You don’t need to be an expert on butterflies. You just need to give a few minutes in July or August to count butterflies near your house.
The count is coordinated by Butterfly Conservation, the UK’s biggest butterfly charity.
The count kicked off on Friday 17 July and runs until Sunday 9 August, to help scientists see what’s happening with some of our most common and much-loved butterflies.
The Big Butterfly Count asks people to spend just 15 minutes outdoors in a sunny spot, count the butterflies and day-flying moths they see, and submit their sightings via the free app or at www.bigbutterflycount.org.
This year’s Big Butterfly Count carries greater urgency than ever. In 2024, Butterfly Conservation declared a butterfly emergency after numbers fell to their lowest level in the survey’s history, and in 2025 the charity launched a rescue mission to help reverse long-term declines.
Around 80% of UK butterfly species have declined over the past 50 years, the result of habitat loss, climate change and pesticide use, and scientists need as many eyes as possible looking for butterflies this summer to see what’s happening. Every sighting counts.
The Peacock, Red Admiral and Holly Blue can all be recorded as part of Butterfly Conservation’s Big Butterfly Count, along with 17 other butterflies and day-flying moths.
