This was my first introduction into why
native bees are so much better pollinators than honey bees.
At first, I assumed she was a honey bee, as she was busy stuffing pollen into the pollen sacs on her legs. But then she started rolling around in the flower like a donkey in a sand-pit, scattering golden pollen dust all over the place, including the red spots on the flower, and emerged looking like someone had sprayed glitter dust all over her. From the plant's point of view this is much, much better as they want their pollen to be transferred to the next flower, not stuffed neatly into pollen sacs to be used as bee food!
Here's another one, a big fluffy silver one, on the side of a phacelia flower. I've no idea what species these are though.
John - that booklet is fantastic! Well worth downloading.
