Yup.. the males only live a week or two and the females live for a few months.
These are Solitary Bees so they have quite a different lifecycle than Honey Bees.
The Solitary Bees, Mason Bees in my case hatch from those cocoons in the pictures and then find pollen, nectar and mud and build homes in the bee boards I made for them.
The smaller cocoons are males and bigger ones are females.
Early next spring I'll be doing alot of content on them. Right now they are all resting.
