Big Butterfly Count
July 18, 2025-August 10, 2025 -
UK, UK
Launched in 2010, the Big Butterfly Count began as a way for the people all over the UK to help assess the health of the environment by working together to count the butterflies in their local area. After more than a decade since it began, the Big Butterfly Count has become the world’s biggest survey of butterflies – with more than 100,000 people participating in 2021.
The Big Butterfly Count is put on by the Butterfly Conservation and typically takes place for three weeks starting late July. Individuals in the UK can submit their counts at any time during the period. The results are tallied and made available to the public, including the numbers and different species of butterflies along with some day-flying moths.
