Twelve dormant cocoons come in a small cardboard container. At this time of year the cocoons will remain dormant during shipping but we ask that you store the container in a safe spot in the refrigerator when you receive them. About a week before crops begin to bloom, be sure the nest has been cleaned and prepared, and secure the box of cocoons to the nest. As the sun warms the nest, the mason bees will begin to emerge. Emergence can take hours or several days. Males will emerge first, then the females. Osmia lignaria propinqua. Feel free to contact us if you have any questions at 1-888-804-8820.
