At the bottom of my garden is a very vigorous Buddleia Globosa. Every two or three years I cut it hard back and within a year it is back up to size - about 7ft high and 7ft wide. At the moment it is a riot of yellow / orange ball shaped flowers.
Just before tea time I wandered down with the camera to see what insect life was being attracted. It was swarming with bees, dozens of them all working hard flitting from ball to ball. They were all of the same black, yellow and orange colouring which I think may be Bombus pratorum. The bush certainly looked like bee heaven by the numbers attracted to it.
Yummy, Yummy - sweet nectar.
