The Big Butterfly Count 2021 takes place from Friday 16 July until Sunday 8 August. People from East Yorkshire and Holderness have been taking part in the annual survey since it started in 2010. Many people choose to do this as a family outing.
The count involves people downloading a butterfly identification chart and spending 15 minutes in a garden, park or on a walk, and counting the butterflies they see. The results are then logged online. There is a free app to download which makes everything so much easier! Take your camera/mobile phone and try to get some pictures too!
