Today was the final stage for the Mason bees life cycle. I took the larvae out of the hive and washed off the light cement-like covering. The directions warned there may be mites but there were none in sight. They are now drying before I put them into boxes and store them in the refrigerator crisper until spring blossoms appear.
We had purchased 30 bees and those bees produced 56 larvae. No idea how many will hatch in the spring.
