I saw where you thought it was odd that a Spider Wasp would hunt a Garden Spider. Thought I’d throw you a little of my own ”evidence”!
Taken in Central Arkansas, btw.

Blue Black Spider Wasp preys upon Orbweaver
Hi Alan,
Thanks so much for sending your photo. Our statement was based upon information posted on BugGuide and not upon any research in books. Scientific theories are based upon observations, and the camera has provided a marvelous tool to assist in observation and the gathering of data. It would be interesting to determine if certain species in the Blue Black Spider Wasp genus Anoplius have a preference for Orbweavers. When one clicks upon the browse button while on the Anoplius genus page on BugGuide, instead of getting the choice of species, one gets the choice of subgenera, and only upon browsing the individual subgenera do actual species come up. Perhaps an expert in the field will be able to provide us with a comment the clarify if any of the species in the genus Anoplius have evolved a set of spider hunting skills that enable them to specialize in hunting Orbweavers. Thanks again for sending us your documentation.
