My colonies were enjoying ours last week (I planted 1000+ bulbs down the orchard where they live a couple of years ago, as well as ones in the garden...) - all of them piling crocus pollen, and some other luminous yellow and pale white pollen in.
Not too bad considering it is zoomed in from a photo taken on my phone.
Taken last wednesday, one of my girls coming in to land with baskets full. I like how she is using one wing to control her landing and the other to propel herself. I love bees!
