The big butterfly count is a nationwide survey aimed at helping us assess the health of our environment. It was launched in 2010 and has rapidly become the world's biggest survey of butterflies. Over 36,000 people took part in 2016, counting almost 400,000 individual butterflies and day-flying moths across the UK (see the 2016 results). big butterfly count 2017 will take place from Friday 14 July to Sunday 6 August.
