I was working in the garden the other day and I saw a small heap of cut leafs so I wanted to flatten it and all of a sudden the heap began to buzz !! Then I saw the bee’s. That was 2 days ago, by now they are rebuilding the heap but it is not yet as high as it was. I looked them up in a book about bees and they are farmworm bees (colletus daviesanus).
THIS IS THE FLATENED HEAP MADE OF CUT LEAFS
THE ENTRANCE OF THE NEST IS UNDER THE YELLOW TWIG, ALAS THEY WERE TOO FAST FOR MY CAMERA TO GET A PHOTO OF THEM
