Well the Red Mason Bees have been busy.
I also provide short pieces of Cane and Plant Stalks for over wintering Lady Birds. Stacked in my old Chicken feed housing they make an ideal environment for for Bees also.
The Red Mason Bees have adopted these as nurseries.

Having filled the whole tube with cells provisioned with Pollen/Honey and laid eggs it is time to seal the end with clay.

So there the eggs hatch feed and develop. The males hatch first so how does this operation take place?
Apparently if a male eats his way out of his cell and finds an immature larvae in the next cell he moves it and its food supply down and seals it back up. Proceeding all the way to the outside world carrying out the same procedure. Wow.
