It’s great to have a hedge buzzing with bees. I’ve just reported these Yellow and Black Bumblebees on The Great British Bee Count website.
You can record your bees at: http://www.greatbritishbeecount.co.uk/seen-a-bee.php or download the free app
The website and app help you to identify them. They’re not out there trying to sting you and if you act calmly they’ll just carry on doing their business and leave you alone..
