I finally, and possibly at the last minute, got around to putting up the nesting tubes I had gathered for solitary bees. As luck would have it I had the roof from a failed birdhouse attempt that a soup can fit into nicely. I jammed the bamboo firmly into the can and wired it to the underside of the roof.
Since the roof is so much wider than the can I took advantage of the extra space and hung a bundle of turtlehead stem sections below and to the side of the bamboo can. Now it’s just a waiting game to see if any bees find these accommodations inviting!
