I visited Holden Arboretum on a great sunny day. While I was there, the bumble bees were hard a work pollinating all of the flowers.
Since bumble bees don't sting, I worked up my bravery and got close enough to the flower to take this photo.
I love the fact that you can see the bee is covered with pollen. It took some trickery because I didn't have a macro lens, but had to shoot with a wide angle.
