The Big Butterfly Count 2025 is between the 18th of July and 10th of August.
Counting butterflies can be described as taking the pulse of nature and we depend on you, our citizen scientists, to help us assess how much help nature needs. The data from this and other counts will also help us to identify important trends in species that will assist us in planning how to protect butterflies from extinction, as well as understanding the effect of climate change on wildlife.
We thank the 2329 people who took part in the Big Butterfly Count 2024 in Norfolk during the summer counting 27,885 butterflies and day-flying moths.
Gatekeeper was our number 1, jumping from 4 th place in 2023. Despite this its numbers were
still down by over a quarter. Our chart topper last year Peacock fell to number 5 with its
numbers down by an average of 70% per count, Red Admiral at number 2 in 2023 slipped to
number 6 with a 75% reduction.
We achieved good coverage for Norfolk, but there are a few gaps (see map). Can you help us fill these in 2025?
