We took some time recently to take out the old tubes of mason bee cocoons and replace them with fresh, new paper tubes. These tubes are where the new female mason bees will lay their eggs, fully provisioned with pollen. These eggs will hatch and the larvae will eat and grow until they are large enough to spin a cocoon and wait out the cold winter all snug and cozy. In the spring the males hatch first and wait for the females. It is at this time that the mason bees provide their renowned pollinating services to flowering fruit trees. As you see in this picture, one of our youngest volunteers is helping to remove the old mason bee tubes and putting them in a special box where the bees can safely hatch out.
