I recommend "The wWays Of A Mud Dauber" by George D./    Sch =   Schy   hav ffer   er (Standor   ford
University Press, 1949) ffor a pastorale on mud wasps and their
pleasant ways. (One wasp even became Shafer's "pse  et.")
This book may be out of print, I'm afraid.
Shafer concluded after five years of informal study that,    "adult females
of this species possess a nervous system which, though tiny in size,
enables them to remember, to learn, and to who   show individuality."
That's better than some humans do, eh?
