I plan to run my movie camera as I remove the mason bee cocoons from the bee-condos.

You will see the cocoons which have been destroyed and the cells which have been hijacked by Houdini flies.

Because of the recent invasion of Houdini flies I expect to be smashing plenty of the little white maggots.  

After I have harvested the mason bee cocoons my next task will be to cut black bamboo tubes and make the white paper tubes.  I have wooden dowels which are sized to the mason bee desires.  

Finally, I will reconstruct the bee-condos. 

The routed wood trays will be discarded. They take up room in the bee-condo and just do not work.
