Shelter and food for a cold leafcutter

I pity the leaf-cutter bees on cold or wet days. They really are sun-loving bees and when the weather is not to their liking they hide in the bee hotel, peeking out of the holes, hoping for the sun to appear. I found this cold male Megachile willughbiella clinging to a hardy geranium flower after a shower a few days ago. Geraniums are one of their favourite flowers, and they also makes a handy umbrella.
