Your letter to the bugman:  Encountered this Spider wasp attempting to haul off his bounty today…wolf spider. A rather large wolf spider at that.
Respect for anything that takes care of these nasty spiders for me.

Spider Wasp with Wolf Spider Prey

Dear Stefanie,
Only female Spider Wasps hunt for prey to feed the brood.  We agree your wasp is
Entypus unifasciatus, 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.”

Correction:  January 23, 2018
In reference to the August 22, 2018 photo of Entypus unifasciatus from Oklahoma City, OK by “Stephanie,” the host spider is Syspira sp. (Prowling spider)(Miturgidae). Of 414 host records for this species of wasp, this is the first host record (1/414, 0.02%) for this family of spider. We do, however, have the same genus and family host record for the congener Entypus aratus from Mexico. We should like to acknowledge “What’s That Bug” and Stephanie for this extremely rare and highly unusual host record. Does Stephanie have a last name to accompany this record in our forthcoming publication on spider wasps? Thank you. Keep up the good work.

Retraction of Correction:  March 4, 2019
When I first saw the image I thought it was a lycosid (wolf spider).  I sent it to an arachnologist at the CAS and he identified the spider as Genus Syspira, Family Miturgidae.  Since then I have consulted two other arachnologists, one from SDSU in CA, and they both informed me that the genus Syspira does not occur in Oklahoma.  They checked hundreds of museum records for this genus through a third arachnologist at Colorado State University and the genus does not occur in SE CO nor in N Texas.  They think the spider is in the genus Hogna (Lycosidae) but cannot be certain because, unfortunately, they cannot see the eye arrangement from the side view photograph.  I’ve sent your higher resolution out for additional study but, since the genus Syspira does not occur in Oklahoma, this is probably a moot exercise.  Thank you for your effort in aiding this identification dilemma.

Your letter to the bugman:  Found my dog barking  and observed it was a fairly large spider I have not seen before. Was curious to find out which it is.

Wolf Spider

Dear Glenn,
This looks to us like a harmless Wolf Spider in the family Lycosidae.

Your letter to the bugman:  Good day,
I found this spider in my house and just want to make sure my identification is correct, is the spider a wolf spider? And if so are they to be considered dangerous for humans?

Female Wolf Spider with Spiderlings

This is indeed a Wolf Spider.  She is a female with her brood of Spiderlings.  Wolf Spiders are considered harmless to humans.

Hi: I am sending two pics of what I believe are the same spieces of spider. One of the spiders is, what I think to be, quite a unique color. I stupidly forgot to put a coin by that one, however, it was just slightly bigger than the second spider. Both spiders were discovered dead. One was being drug by a spider wasp. We have had a bumper crop of spiders this year. They seem to have exploded along with the record breaking rain in our area. Thank you for checking my photos and I am very curious about the one with the blue abdomen.

Wolf Spider

Dear Kathy,
These are not Trapdoor Spiders, and we concur that they are probably Wolf Spiders and the same species or at least genus.

Update Courtesy of a comment from Michael
Michael identified these as members of the Wolf Spider genus
Tigrosa, and based on this BugGuide image and this BugGuide image, we would grade his as Correct.

What is this wasp dragging a spider across the deck? The iridescent blue wings and striped body, rusty colored legs and eyes are beautiful. It was very fast but I was able to get a very short video of it.

Spider Wasp with Prey

Dear Dawn,
This is a Spider Wasp in the family Pompilidae, and female members of the family hunt and paralyze Spider to feed to the developing brood.  Your species,
Tachypompilus ferrugineus, does not have a species specific common name.  According to BugGuide:  “Adults are often found taking nectar from flowers (Daucus, Pastinaca, and Eryngium). Females provision nests mainly with Lycosids” meaning the Spider in your image is most likely a Wolf Spider.

Spider Wasp and Prey

Thank you Daniel. It is extraordinary that you replied so quickly and it is much appreciated. I will write a short story for the Bert Miller Nature Club’s fall Rambler newsletter and give reference to What’s That Bug and the information you provided.

I cannot find anything about why this wolf spider is pink? I found it today shoveling dirt in my yard.
I have several pictures if you’d like more.
Thank you!

Wolf Spider

Dear Angelina,
We are pretty sure your Wolf Spider is a Carolina Wolf Spider,
Hogna carolinensis, a species that can be highly variable in color.  Individuals found in desert areas are frequently light or white in color like this BugGuide posting from Arizona or this BugGuide posting from Utah, and this individual posted to BugGuide from Montana is also white.  We would love to see additional images, especially a ventral view.
