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.

Daniel was out working in the yard when he spotted a large, metallic green wasp well over 1 1/2 inches in length.  Alas, there was no camera handy and the wasp quickly flew off after running on the ground for a few seconds with an agitated style and its wings quivering.  Upon some research, and comparing images on The Natural History of Orange County and on BugGuide, Daniel believes it was a Tarantula Hawk, possibly
Pepsis mexicana, and that is why this image from our archives is being used to illustrate this new posting.

Spider Wasp and Wolf Spider Prey

Dear Christopher,
Thanks so much for submitting your awesome image of a Spider Wasp,
Entypus unifasciatus, and its Wolf Spider prey.  The Wolf Spider will not be eaten by the Spider Wasp.  She feeds on nectar from flowers, and the paralyzed Wolf Spider will provide fresh food for a larval Spider Wasp which will eat its paralyzed meal alive.

Tarantula Hawk

Dear Marlon,
This appears to be a Tarantula Hawk in the genus
Pepsis, or a closely related genus.  Female Tarantula Hawks prey upon Tarantulas and Trapdoor Spiders, stinging them to paralyze them.  The paralyzed Tarantula is buried after the female Tarantula Hawk lays an egg.  When the egg hatches, the larva feeds on the still living, but paralyzed Tarantula.

Spider Wasp

Dear Shara,
Tarantula Hawks are Spider Wasps in the genera
Pepsis and Hemipepsis that prey on Tarantulas, and according to BugGuide data, the latter genus is not found as far north as Idaho, and similarly, BugGuide data on the genus Pepsis also shows a more southern range.  Other Spider Wasps have similar coloration.  Your individual might be Calopompilus pyrrhomelas which is pictured on BugGuide and reported from Idaho based on BugGuide data.

Are they dangerous, or like a normal sting or bite?   I picked it up with a leaf , and put it in the sun.   It was cold on my porch.

Spider Wasps are not aggressive towards humans, and Tarantula Hawks are reported to have very painful stings.  Since your individual is also a member of the tribe Pepsini that includes Tarantula Hawks, it might also have a painful sting.  Again, Spider Wasps are not aggressive, but they can sting.

Spider Wasp with Prey

Dear Alissa,
Your images of a female Spider Wasp with her prey are awesome.  The Spider wasp is
 Entypus unifasciatus and the prey is likely a large Wolf Spider.
