Following a poor year for butterflies in 2016, Sir David Attenborough is urging the public to survey butterflies and report their sightings to Butterfly Conservation.
The natural history presenter described 2017 as a “critical summer for butterflies” as many common species are in decline in Britain.
2016 was the fourth worst year on record for the insects.
“Last year, despite a warm summer, butterflies like the small tortoiseshell, peacock, meadow brown and gatekeeper saw their numbers fall,” he said.
“A warm winter and cold spring earlier in the year led to problems that affected their numbers later on.”
In the last 40 years, more than 75 per cent of the UK’s butterflies have declined, and new research from Butterfly Conservation shows that butterfly numbers in urban areas are decreasing faster than populations in the countryside.
Attenborough said, “Your sightings will tell us which species need help and in which areas we need to help them.
“But the Big Butterfly Count is also good for you because 15 minutes spent watching butterflies in the summer sunshine is priceless; spending time with butterflies lifts the spirits and reinvigorates that sense of wonder in the natural world.”
