SIR David Attenborough is calling on Trafford to become back garden wildlife detectives this summer by taking part in the world’s largest butterfly survey.

Butterfly Conservation president Sir David will take part in citizen science project the Big Butterfly Count in an effort to count 1 million butterflies between July 19 and August 10.

The creatures rallied last summer after their worst year on record in 2012 and good weather this July and August could help Big Butterfly Count participants count a million butterflies for the first time since the Count launched in 2010.

He explained: “The UK is a nation of amateur naturalists and we have a proud tradition of celebrating and studying our wildlife.

“By taking part in the Big Butterfly Count this summer you can contribute to this heritage and discover the fantastic butterflies and other wildlife that share your garden, parks and countryside.
