People are being urged to help measure the scale of Britain’s butterfly bounceback after last summer’s dramatic decline with this year’s launch of the world’s biggest insect survey.
The Big Butterfly Count asks volunteers to spend 15 minutes in a local green space counting the butterflies and day-flying moths they see. Results of the survey, which takes place from 18 July to 10 August, can be logged on the Butterfly Conservation charity’s website or via its free app.
