And I still raise them, The Orchard Mason Beees have completed their development and are now adults hibernating until next spring. I am removing the cocoons from the nesting blocks and will put them in the refrigerator for the winter.
They are called Mason Bees because they use clay to separate each nesting cell. If you want to know more you can find my book "The Orchard Mason Bee" at Village Books, on Amazon or on line at Knox Cellars Mason Bees.
