Wasp Saga.

     A female mud dauber wasp loading her mud chamber with a spider that the developing baby wasps will eat.

                One sealed chamber and one still waiting for a tasty morsel to be placed inside.

                                       Both chambers covered with a protective layer of mud.

The empty pupa case of the new wasp still in place with the other chamber completely empty.
