This bee, cuts the leaves of roses and buddleias to weave the cells for their young - they are one of the world's most amazing bees and are Australian natives. I never see the bees, but I do see the result, I will have to keep looking!
I've only ever seen one once, and I took a blurry photo (that I posted) that was not great at all. It was amazing to watch them roll up the circle, and fly it to the nest.
