Famed naturalist and TV personality Sir David Attenborough has asked for people to spend 15-minute periods counting as many butterflies as they can see.
The wettest April for a century and the dampest June on record has left lepidopterists wondering how Britain’s 59 butterfly species have fared.
Nearly three-quarters of the winged insects are already in decline and one-third are at risk of extinction, according to Butterfly Conservation.
The fact that every single person can produce a statistic that is of real value is a great spur,” said Attenborough.
“Many people will for the first time start taking a careful and critical view of their surroundings. The butterfly count helps butterflies but it also helps natural history and eco-sensitivity in this country.”
The group’s Big Butterfly Count asks people to record online all of the species they spot in their garden or at a local park.
