The results of this year’s Big Butterfly Count have been released, showing encouraging numbers across Sussex.
More than 4,500 people took part in the three-week survey, spotting over 67,000 butterflies and day-flying moths, that’s a 15 per cent increase on last year.
But Butterfly Conservation says urgent action is still needed to tackle the long-term decline in butterfly populations.
Butterflies need two things to thrive: good weather and a healthy environment.
Dr Richard Fox, Head of Science at Butterfly Conservation, warns that “We may feel like we’ve seen lots of butterflies this summer, but that’s only because last year was so awful.
“Last summer’s results were the lowest we’ve seen and a stark warning that many of our common butterfly species are facing significant pressure from challenges linked to habitat loss, climate change and pesticide use.
“Whilst we’ve seen noticeably more butterflies during 2025’s Big Butterfly Count, the figures suggest it’s actually been a pretty average year for them by modern standards.
“The 15-year Big Butterfly Count trends show that more than twice as many widespread species have declined significantly than have increased. And, while most species had a better than average summer, one-third of species fared poorly even in the generally beneficial weather.
“There remains a need for us to take urgent action to support our butterfly populations, including by improving the environment in which they live, restoring habitats and reducing pesticide use. Until we do these things we are unlikely to see a great recovery in butterfly numbers, regardless of how much the sun shines.”
Butterfly Conservation has launched a rescue mission for the UK’s butterflies and is asking the people of Sussex to sign its open letter to retailers calling for the removal of toxic synthetic pesticides from sale for domestic use. You can add your name by visiting www.butterfly-conservation.org
