The Great Sunflower Project

Hi,

I took some photos of bees in the yard but I am having a hard time id'ing them. Can anyone help? I've posted the photos on picassa. Follow the link. The last photo is the one I am really curious about as I have many of these in the yard.

Thanks for your help!
Anna

If that doesn't work, I'll upload a photo too.
