Butterflies and moths across the UK are currently facing significant environmental challenges as their natural habitats continue to decline. Conservationists warn that monitoring these delicate insects is now more important than ever to ensure their long-term survival.
National Initiative to Champion Favourite Species
To highlight this urgency, a new national initiative is inviting residents to champion their favourite species through a public vote. The project aims to foster a deeper appreciation for the vital role these pollinators play in our local ecosystems. By naming a 'national favourite', organisers hope to inspire more people to look closer at the wildlife in their own gardens. This celebration of British nature precedes a major scientific effort to track population trends across the UK.
The Importance of Counting
Kate Merry, from Butterfly Conservation, said: “Over the last 16 years, more than 1.35 million counts have been done by hundreds of thousands of people across the UK, spotting almost 13.8 million butterflies and helping us with our vital science and conservation activities. This year, we can’t wait to celebrate a bumper summer of butterflies by holding the first-ever vote to discover Britain’s Favourite Butterfly, before welcoming back the 17th annual Big Butterfly Count. Will the nation’s favourite species go on to reign supreme in the Count? Save the dates in your diaries to take part and help us find out.”
Britain's Five Most Threatened Butterflies
While many of our garden visitors are thriving, half of Britain’s remaining butterfly species are now on the official Red List. According to the latest scientific assessments, eight species are classified as Endangered, with many others facing a high risk of extinction due to habitat loss and climate change. The following list highlights the species currently facing the most significant challenges in the UK.
- High Brown Fritillary: Once widespread, this is now one of our rarest butterflies. It is restricted to a few sites in the West Country and Morecambe Bay, where it relies on specific woodland management.
- Grayling: This master of camouflage has seen a dramatic 90% decline in parts of its range. It is a 'specialist' that needs coastal dunes or heathlands to survive.
- Wall Brown: Known for its 'eye' markings, this butterfly is struggling with climate change. Warmer autumns are tricking it into a 'developmental trap' where it emerges too late in the year to breed successfully.
- Large Heath: This species is particularly vulnerable as it lives in peat bogs and moors. As these damp habitats dry out due to rising temperatures, its population continues to shrink.
- Wood White: A delicate, slow-flying butterfly of ancient woodlands. It has vanished from many of its historical haunts as traditional forest management, like coppicing, has declined.
How You Can Take Part
The search for Britain’s Favourite Butterfly officially opens on Friday, May 15, and will run until Sunday, June 7. Voters can choose between iconic species like the vibrant Peacock, the hedgerow-loving Gatekeeper, or the migratory Painted Lady. Following the vote, the 17th annual Big Butterfly Count returns from Friday, July 17, to Sunday, August 9. Participants are asked to spend just 15 minutes in a sunny spot, whether in their gardens or the wider world, to record the different species they see. Every submission provides essential data that helps scientists understand how climate change and habitat loss are affecting local populations. You can find more information on how to register and cast your vote at Butterfly Conservation.
