Yesterday, after working my two hives, I was watering plants on my patio, when out of the corner of my eye I saw what I thought was one of my honey bees with a huge load of white pollen. When I could finally step back far enough to focus on her, what I saw was a small bee carrying a rolled up piece of flower petal. She carried it head first into the throat of a scarlet mandevilla, unfurled it, and spent a minute or so tacking it down, then flew off. Within a very short time she was back with another, then another, and another. I think she probably brought in six or seven bits of some white petal before she climbed into her flowery bower, and rolled herself tightly round with her covers. I've never seen any thing like it and have been unsuccessful at finding out what kind of bee she might be. Any ideas?
