These bee tube paper liners are designed for solitary bee management. Instead of just encouraging the bees to lay in drilled wooden canes or cardboard tubes where development of the bee cells is concealed from view, the bee tubes may be lined with these paper management tubes so that the paper liners containing bee cells can be withdrawn and examined and even replaced into other bee nesters. The paper tubes are semi-transparent and can be untwisted to reveal the bee cells and larvae within. This is particularly helpful if you need to monitor aspects of the solitary bee lifecycle in detail and also allows the inspection and removal of solitary bee parasites thus allowing health management of your solitary bees.
