When the nest site has been cleaned and prepared, secure the box of cocoons to the nest site. As the sun warms the nest site, the mason bees will emerge. Emergence can take hours, or several days. Males emerge first, then the females. Osmia lignaria propinqua. Feel free to contact us if you have any questions at 1-888-804-8820.
