Back in May of this year, I had a number of inquiries about Leafcutter Bees, and posted a note about Leafcutter Bee nests from bee expert Stephen Buchmann (click here to read his response). Corinne, in Paradise Valley, Arizona, kindly sent along this terrific photo to show her new bee nest in action (click the photo to enlarge). Note that it's essentially a collection of bamboo tubes bundled together. The bee has been lining each tube with leaf pieces to create cells, laying an egg and a food supply in each cell, and then capping off the ends with more leaf. A very simple and effective way to host these great pollinators in your yard.
