Big Butterfly Count gets underway

94adc848-ef58-41c8-af9c-d864cb7f90ae

Butterfly Conservation is calling on people across the country to take part in this year's Big Butterfly Count to help scientists understand the impact of climate change on our most-loved butterflies.

This year's Count takes place between 14 July and 6 August.

Last summer's record temperatures, heatwave and drought caused some of the plants that caterpillars feed on to wither and die. To help scientists discover what the ongoing impact of this extreme weather has been, members of the public are being asked to spend 15 minutes in any sunny spot and record the number and type of butterflies they see.


In 2022, more than 100,000 Counts were conducted by members of the public for Big Butterfly Count (Chris Teague).

Butterflies are indicators of a healthy natural environment – with half of Britain's butterfly species already threatened or near-threatened with extinction, it's never been more important to understand how our insects are responding to the changing climate and to take action to protect them.

Dr Zoë Randle, Senior Surveys Officer at Butterfly Conservation explained: "This is a vital year for the Big Butterfly Count. We know that the previous extreme summer droughts in 1976 and 1995 took a heavy toll on butterflies and numbers crashed the following year, taking almost a decade to recover.

"The data collected during this year's Big Butterfly Count will give us a valuable insight into what the effect of the most recent extreme weather has been, and how we might be able to better protect our beautiful butterflies. With climate change here to stay, we need people to take part more than ever before."

Butterfly Conservation's Big Butterfly Count is the largest citizen-science project of its kind and is a positive way that everyone can help. As well as contributing to important scientific data collection, taking part in the Count is a great way to enjoy time outdoors, connect with nature and have fun.

President of Butterfly Conservation, Sir David Attenborough, has shared poignant messages in his support of the Big Butterfly Count over the years. Sir David commented: "A few precious moments spent watching a stunning Red Admiral or Peacock butterfly feeding among the flowers in my garden never fails to bring me great pleasure."

Butterfly Conservation Ambassador, Dr Amir Khan, is another of the famous faces supporting the Big Butterfly Count. He said: "Getting outside in nature and watching butterflies is a wonderful experience, not only does it spark joy and lower anxiety, you also know that you're having a big impact on informing important conservation decisions. Spending time in nature is proven to be beneficial to our mental health, it can alleviate stress, boost mood and energy, and enhance feelings of happiness."


Day-flying moths, such as Six-spot Burnet, can also be recorded for the Count (Chris Teague).

Whether done with friends and family, or in a moment of quiet calm and solitude, the Big Butterfly Count is free, fun and takes just 15 minutes. It is open to anyone, of any age, in any part of the UK – towns, cities or the countryside. No green space is too small – a back garden, a small terrace or balcony with some pot plants, a public park, allotment or country lane are all important spaces to explore, track and report.

Last year almost 100,000 Counts took place up and down the country, with participants spending a combined 2.5 years counting butterflies in their gardens, local parks and in the countryside. The information gathered helps to inform conservation projects, government policies and supports other experts with their research and vital work to protect our planet.

Dr Zoë Randle added: "We know 80% of butterflies in the UK have declined since the 1970s. Which means there are fewer butterflies to be seen than in years gone by. However, even if you don't see any butterflies during your Count, we still want you to tell us! We need to know where there aren't any butterflies just as much as where there are, so please still log your results and then pick another day or location and try again. There are no limits on how many times you can take part."
