Spider Wasp and prey

Hi Belinda,
This is definitely a Spider Wasp.  Based on this BugGuide image, it appears to be
Entypus unifasciatus. The prey appears to be a Fishing Spider in the genus Dolomedes, and according to BugGuide:  “Females dig a burrow that ends in a terminal chamber off of the side of a mammal burrow or large crack in the ground. The serrations on the hind tibiae are used to aid the movement of soil out of the burrow entrance. The position in which the egg is laid is unknown. Larvae feed on one large spider and, as in all Pompilids that have one generation per year, overwinter as pupae.”  Most images of this Spider Wasp are with prey that are Wolf Spiders like this BugGuide image, but Fishing Spiders surely constitute “one large spider.”  Perhaps an expert in Spider Wasps will be able to provide comments regarding the prey.
