A wildlife charity has declared a national “butterfly emergency” after its annual Big Butterfly Count recorded its lowest ever numbers.
The count has been running for 14 years. This year’s poor results are partly down to the wet weather but the long-term trend is hugely concerning, says Butterfly Conservation.
It is calling on the government to ban pesticides that can harm butterflies and bees “before it’s too late”.
Butterflies are at “their lowest ebb” on the back of 50 years of decline, said the charity’s head of science, Dr Richard Fox.
“Butterflies are a key indicator species; when they are in trouble we know that the wider environment is in trouble too,” he said.
Neonicotinoid pesticides were banned in the UK in 2018 but have been approved four times in a row in emergencies to tackle a virus that attacks sugar beet.
A spokesperson from the Department for Environment Food and Rural Affairs said it was “committed to deliver for nature and will change existing policies, including banning the use of those neonicotinoid pesticides that threaten vital pollinators” – but has given no time scales for doing so.
The 2024 Big Butterfly Count took place in July and August across the UK when thousands of people recorded over a period of 15 minutes how many butterflies they saw, even if it was none.
Overall, participants spotted seven butterflies on average per count, the lowest in the scheme’s 14-year history. Last year’s average was 12.
Butterfly Conservation said it was the worst year recorded for the common blue, holly blue, green-veined white, small white, small tortoiseshell, painted lady and Scotch argus.
