Big Butterfly Count 2025

Friday 18th July to Sunday 10th August

Following the lowest numbers on record from last year’s Big Butterfly Count, Butterfly Conservation have declared a butterfly emergency.

Why It Matters

Butterflies are powerful indicators of environmental health. Changes in their numbers can reveal the effects of pollution, habitat loss, and climate change. Many UK species are in decline – with last year seeing the second-lowest butterfly counts since records began in 1976.

The Big Butterfly Count is a national citizen science project run by Butterfly Conservation, designed to help monitor the health of our environment – and anyone can take part.

How to Get Involved

Taking part is easy and only takes 15 minutes:

1. Pick a sunny spot – your garden, a local park, or anywhere outdoors.

2. Count butterflies and day-flying moths – record the highest number of each species you see at once.

3. Submit your sightings via the free Big Butterfly Count app or online at bigbutterflycount.butterfly-conservation.org.

You’ll also find handy ID guides and resources on their website to help identify what you’ve seen.
